On a Hauni Protos-M8 rod maker running 12,000–14,000 rods/min, the side seam adhesive is transferred from a chilled steel roller through a 0.18–0.25 mm doctored gap to a 26.5 mm wide cigarette paper moving at 280–320 m/min. The interval from adhesive deposition to garniture folding is 0.25–0.45 s. As-received JZ-I VAE emulsion at 52–54 wt% solids and 2,500–3,500 mPa·s measured by ASTM D2196-20 with Brookfield RVT spindle #4 at 20 rpm and 25°C is too viscous to transfer cleanly; it forms a roller film above 0.04 mm and slings adhesive onto the garniture belts. Dilution with 10–18 wt% demineralized water of conductivity below 10 µS/cm lowers viscosity to 1,600–2,200 mPa·s and solids to 48–50 wt%. Calcium hardness above 25 mg/L as CaCO3 destabilizes the PVOH-protected colloid and produces insoluble roller build-up within 30–40 min of recirculation. Dry add-on is controlled at 0.5–0.9 mg/cm² of overlap area, determined gravimetrically after 2 h at 105°C in a forced-air oven. Bond pH is maintained at 4.5–5.5; cigarette paper containing more than 25 wt% calcium carbonate filler can react with adhesive below pH 4.0 and form micro-foam at the bond line. Seam tensile strength is evaluated according to TAPPI T 494 om-13 on 15 mm wide strips after 24 h at 23°C/50% RH, with target wet strength retention above 60% after 5 min water immersion. Because the system does not contain a thermosetting crosslinker, storage of finished rods above 40°C and 75% RH for more than 72 h can plasticize the dry film and cause seam reversion downstream on tray fillers. For North American packaging buyers, adhesive compliance is assessed under 21 CFR 175.105, although the cigarette rod itself is not a food-contact article.
Plug wrap paper of 24–28 g/m² and air permeability of 5,000–8,000 cm³/(min·cm²·kPa) according to ISO 2965:2019 is bonded to cellulose acetate filter rods at 400–600 m/min. JZ-I is diluted with 20–30 wt% demineralized water to 800–1,200 mPa·s before application through a Mayer bar or slit nozzle, giving a dry add-on of 12–18 g/1,000 filters. The immediate dry film has a glass transition temperature of approximately -5°C, which remains below 0°C to prevent brittleness during filter rounding. Triacetin plasticizer, present at 6–8 wt% in the cellulose acetate tow, migrates into the adhesive layer over 7–14 days at 25°C. This migration reduces the T-peel force measured by ASTM D1876-08(2023) by 10–20%, but values remain above 0.30 N/15 mm when dry add-on is below 1.5 g/m². At add-on above 2.2 g/m², the plasticized film softens further and causes blocking deformation of stacked filters after 14 days at 40°C and 75% RH. Accelerated ageing per ISO 5630-3:1996 at 80°C and 65% RH for 48 h must not produce yellowing; pH is held at 4.5–5.5 to avoid alkaline browning of the bright white plug wrap. Compliance for European filter converters typically references EU Regulation (EC) No 1935/2004 Article 3 and BfR Recommendation XIV for polymer dispersions in paper contact.
Cork tipping papers of 38–45 g/m² with low-porosity printed surfaces require a lower-viscosity VAE film than side seam work because the adhesive must wet a partially sealed surface and still transfer from a chromium-plated gravure cylinder. As-received JZ-I at 2,500–3,500 mPa·s is reduced to 1,000–2,000 mPa·s by adding 15–25 wt% demineralized water; every 1% water addition represents approximately 0.4–0.5 wt% solids reduction and shortens open time by 2–4 s at 23°C/50% RH. The gravure cylinder, typically 80–100 lines per inch, deposits 22–35 g/1,000 cigarettes wet. Bonding to the tobacco rod and filter plug is set on a heated drum at 80–120°C with contact time of 0.2–0.4 s. Adhesive film with open time below 20 s causes early skinning on the gravure cells and dotted transfer; open time beyond 45 s produces fibre-tearing tack that interferes with clean cutting. Borate-based cleaning agents are incompatible: borate ions crosslink residual PVOH and raise viscosity above 5,000 mPa·s within minutes, causing stringing and machine stoppages. Cleaning is carried out with 40–50°C demineralized water only, followed by complete drying of the glue tray before recharge. Peel force measured by ASTM D1876-08(2023) should fall between 0.25 and 0.45 N/15 mm after 24 h; values above 0.60 N/15 mm are associated with paper splitting when the finished cigarette is ejected from the pack.
| Application stage | Machine speed | Diluted viscosity | Dry add-on | Primary failure window |
|---|---|---|---|---|
| Rod side seam | 10,000–14,000 rods/min | 1,600–2,200 mPa·s | 0.5–0.9 mg/cm² | Open time below 0.25 s or calcium hardness above 25 mg/L CaCO3 |
| Filter plug wrap | 400–600 m/min | 800–1,200 mPa·s | 12–18 g/1,000 filters | Dry add-on above 1.5 g/m² combined with triacetin migration |
| Tipping paper | 200–350 m/min | 1,000–2,000 mPa·s | 22–35 g/1,000 cigarettes | Open time below 20 s or peaking above 0.60 N/15 mm |
| Foil/paper innerliner | 150–250 m/min | 3,000–5,000 mPa·s | 3.0–4.5 g/m² wet | Residual moisture above 1.0 wt% before re-winding |
For an innerliner consisting of 6.3 µm soft aluminium foil laminated to 28–32 g/m² paper, JZ-I is applied at 3.0–4.5 g/m² wet on a 150-lines-per-inch rotogravure station at 150–250 m/min. Drying at 100–140°C reduces residual moisture to below 1.0 wt%; above 2.0 wt% residual moisture in re-wound logs causes blocking after 24 h at 40°C because the PVOH-protected film remains hygroscopic. Blocking resistance is measured under a 250 kg/m² stack pressure at 40°C/80% RH for 48 h, with a release force target below 0.35 N/25 mm. Bond strength after 24 h conditioning is evaluated by ASTM D1876-08(2023) T-peel and exceeds 0.50 N/15 mm when paper fibre tear is observed. The dry laminate must withstand folding at -10°C without film cracking, a requirement verified by a 180° fold over a 2 mm mandrel. Because the innerliner is an indirect tobacco-contact material, converters commonly apply 21 CFR 176.170 and BfR Recommendation XIV as export acceptance criteria; residual vinyl acetate monomer below 0.1 wt% by headspace GC is a typical buyer specification. The adhesive is not a barrier coating and must not be used as a printable top coat.
For soft pack outer blanks and hinge-lid cartons, JZ-I is diluted to 250–350 mPa·s with 25–35 wt% water and applied at 0.8–1.2 mg/cm² through Nordson LA-series slot guns on packers running 400–600 packs/min. Compression bonding is established within 5 min at 23°C/50% RH; fibre tear of the glued area above 85% is required before pack filling. Storage above 75% RH can extend open time beyond 60 s and demands air-conditioned glue lines. For China-bound carton stock, the adhesive system is screened against GB 9685-2016 positive-list requirements for food-contact paper adhesives, although the outer carton is not a tobacco-contact layer.
For pre-gummed cigarette tube papers and roll-your-own filter tips, JZ-I is applied as a 0.3–0.8 mm wide line at 2.0–3.5 g/m² dry add-on using a rotary metering wheel at 80–120 m/min. The coated strip is dried to below 1.2 wt% residual moisture and re-wound under controlled tension. Dry blocking is tested by stacking 100 mm × 100 mm specimens at 21 kPa and 35°C/85% RH for 72 h; release force must remain below 0.35 N/25 mm. Rewetting time of the dry film with water at 20°C is 4–8 s, measured by a drop-spread method comparable to ISO 535:2023 but limited to a 1 µL droplet. The terminal tube, typically 24.5 mm circumference, is filled at 120–180 tubes/min; seam opening below 0.5% of tubes is the production acceptance threshold. At storage humidity above 75% RH, the PVOH-protected film absorbs 8–12 wt% water and may remain tacky above 30°C, so polyethylene overwrap is required for long-term distribution.

Cigarette Glue JZ-I VAE Emulsion is a waterborne vinyl acetate-ethylene copolymer dispersion supplied for high-speed cigarette filter-wrap, side-seam, and tipping-paper bonding. The model designation JZ-I identifies a specific protective-colloid-stabilized grade within the manufacturer’s VAE series; the product is not a PVAc homopolymer and is not an ethylene-vinyl acetate hot-melt. The emulsion is cold-applied, aqueous, and protected by a polyvinyl alcohol colloid. Lot-level specifications are recorded on the manufacturer certificate of analysis. Representative specification ranges for this class of VAE cigarette emulsion include nonvolatile content from 50% to 55% by ISO 3251:2019, Brookfield viscosity from 1,500 mPa·s to 4,000 mPa·s at 25 °C by ASTM D2196-20, pH from 4.0 to 6.0 by ASTM E70-19, and glass transition temperature from -10 °C to 0 °C by differential scanning calorimetry per ASTM D3418-15. The JZ-I-specific values are to be verified against the supplier data sheet and retained batch certificate. The ethylene comonomer acts as an internal plasticizer, reducing minimum film formation temperature without requiring dibutyl phthalate or benzyl butyl phthalate. The product is intended for porous cigarette papers, plug wrap, and surface-sized tipping base papers, where it forms a flexible and rapidly setting bond after water loss. Typical machine reel stock moisture content ranges from 5% to 7%, and the wetting and initial tack of the emulsion depend on paper air permeability and surface sizing. Published data for the specific JZ-I formulation are limited; the user is required to qualify the product on the target paper grade.

Wetting of cigarette paper by the JZ-I emulsion is controlled by the dynamic surface tension and the paper’s surface energy. For porous plug wrap with a basis weight of 25 g/m² to 35 g/m², the adhesive must wet the fibre surface without excessive penetration that would stain the tobacco side. Dynamic surface tension of comparable VAE emulsions at 25 °C ranges from 40 mN/m to 50 mN/m; lower-viscosity formulations can show lower dynamic surface tension at high application speed. The JZ-I-specific surface tension is not stated by the manufacturer in this document. The wetting balance is evaluated by measuring contact angle on the target paper or by a dye-stain penetration test at the intended coat weight.
During filter rod manufacture on pneumatic filter makers such as Hauni KDF series equipment operating at 400 m/min to 600 m/min, the JZ-I emulsion is moved through a closed circulation loop to the garniture section by a gear or positive-displacement pump. The adhesive is applied to one edge of the plug wrap immediately before folding; dry add-on in comparable processes ranges from 8 g/m² to 18 g/m². The formulation is expected to provide rapid wet tack development on porous plug wrap, but open time varies with paper porosity and machine speed. Pilot-scale applicator trials are required to confirm tack retention and seam strength on the target paper grade because published data for JZ-I under specific maker conditions is limited. Processors should filter return-line adhesive through a 200 µm strainer before the reservoir and avoid prolonged high-shear recirculation. The rod seam must survive pneumatic transport and cutting without dusting; bond performance is commonly checked by transverse compression and visual fibre-tear tests on the formed filter rod.
Side-seam bonding on cigarette making machines involves a rolling disc or slot applicator delivering the JZ-I emulsion to the overlapping paper edge before the garniture folds the paper into a continuous rod. At maker speeds above 10,000 cigarettes/min, the interval between adhesive application and cutoff is often 0.5 s to 1.5 s. The adhesive should not penetrate through the paper and must remain stable at the machine-running temperature. Oven heat and paper moisture determine final seam strength. Comparable VAE cigarette adhesives are formulated for clean machinability on high-speed makers; JZ-I-specific runnability data are not public and require trial confirmation on the actual maker type and reel stock. Seam strength may be compared by tensile break of the formed rod or by a peel test adapted from ASTM D903-98(2017) using the actual cigarette paper.
Film formation of the JZ-I VAE emulsion begins when water is removed into the paper and by heat from the garniture heater. The minimum film formation temperature should be below the paper temperature at the heater exit; if the adhesive film is dried below its minimum film formation temperature, the seam may appear white and brittle. For VAE copolymers with a glass transition temperature below 0 °C, minimum film formation temperature is typically below 5 °C; the JZ-I-specific value is to be taken from the manufacturer’s data sheet. Drying rate is affected by paper moisture, heater temperature, and machine speed. Incomplete drying before the cut-off head can cause adhesive transfer to cutters and build-up on the garniture belt.
Compared with PVAc homopolymer emulsions, the JZ-I VAE grade contains copolymerized ethylene sequences that reduce minimum film formation temperature and improve low-temperature flexibility. PVAc homopolymer films typically have a glass transition temperature from 28 °C to 33 °C and require external plasticizer to remain flexible on cigarette paper. Plasticizer can migrate from the bond line into the paper or tobacco contact surface and may reduce bond stability over shelf life. VAE ester films with a glass transition temperature below 0 °C retain elongation after cutting and package compression. In 180° peel testing on porous cigarette paper under ASTM D903-98(2017), VAE formulations used in cigarette assembly typically show fibre-tearing failure at lower coat weight than unmodified PVAc homopolymer adhesives. On high-speed makers, VAE emulsions are generally less prone to shear-induced bodying than high-molecular-weight PVAc, but the JZ-I grade still requires mechanical stability evaluation in the actual circulation loop. No published comparative data for JZ-I against a specific competitive PVAc adhesive have been issued; a plant trial on the target machine remains the basis for changeover.
Tipping-paper bonding on modern making machines requires the adhesive film to develop green strength within a fraction of a second before the double-length rod enters the cutting head. The JZ-I emulsion may be applied by transfer roller or slot nozzle on the tipping section; current maker speeds can exceed 10,000 cigarettes/min. The thin high-holdout tipping paper presents different wetting and blocking behaviour than plug wrap, so coat weight and viscosity must be balanced to avoid strike-through, curl, or blocking after packaging. The wet film must transfer cleanly without misting. Comparable VAE tipping adhesives are often adjusted to a Brookfield viscosity at 25 °C of 800 mPa·s to 2,500 mPa·s to reduce misting at high line speed. JZ-I-specific viscosity and tack curves are not published and must be generated on the target paper and maker configuration.
For tipping applications, the selected JZ-I formulation must satisfy two opposing requirements: sufficient 180° peel adhesion to the tipping paper and sufficient blocking resistance under storage pressure. Blocking propensity increases with residual tack of the dried film, especially when stacked cigarette packs are exposed to temperatures above 30 °C and relative humidity above 60%. A formulation with higher ethylene content can reduce blocking, but the same compositional shift may lower initial shear strength. Reported production-scale evaluations of VAE tipping emulsions indicate that the ratio of peel adhesion to blocking force is strongly influenced by minimum film formation temperature and water-release rate. A controlled blocking test using 0.5 kg/cm² to 1.0 kg/cm² pressure at 35 °C for 24 h is used in comparable adhesive qualifications. JZ-I-specific values are not published; evaluation on the target lot is required. The peel adhesion side of the evaluation should be conducted according to ASTM D903-98(2017) using the actual tipping paper and cigarette rod configuration.
The JZ-I VAE emulsion is expected to behave as a pseudoplastic or nearly Newtonian dispersion depending on particle size distribution and protective colloid content. In circulation loops, shear rates in gear pumps and narrow orifices can exceed 10,000 s⁻¹. Mechanical stability must be monitored by viscosity drift and screen residue; ASTM D2196-20 provides a standard Brookfield RVT procedure for comparing fresh and sheared material. The emulsion pH is measured by ASTM E70-19 with a glass electrode on the as-supplied liquid. Coagulation risk increases when the adhesive is contaminated with acidic paper dust or multivalent metal salts; ferric chloride or aluminium sulfate at concentrations above 0.1 wt% can generate macroscopic coagulum. Return lines should be designed for low shear, and a 200 µm to 250 µm strainer is recommended before the applicator. If dilution is required, water should be added slowly under low-speed agitation; high-speed dispersers above 1,000 rpm can destabilize the emulsion. Unlike some PVAc adhesives that are extended with borax or starch, VAE emulsions typically exhibit limited borax tolerance; addition of borax can increase viscosity but may also destabilize the protective colloid. The JZ-I grade should not be compounded with borax without a preliminary compatibility test. Published data for JZ-I specific particle size and shear stability are not available; qualification on the actual adhesive delivery system is required.
| Adhesive class | Glass transition range | Typical solids fraction | Principal operational limitation |
|---|---|---|---|
| JZ-I VAE emulsion | -10 °C to 0 °C | 50%–55% | pH-controlled storage and freeze protection |
| PVAc homopolymer | 28 °C to 33 °C | 50%–60% | External plasticizer migration and higher film stiffness |
| Starch/dextrin blend | not applicable | 40%–60% | Humidity sensitivity and lower high-speed consistency |
Relative to EVA hot-melt adhesives, the JZ-I VAE emulsion does not require pre-melting, heated hoses, or slot-die temperature control. It is waterborne and can be applied at ambient temperature; however, it requires water removal and is more sensitive to freeze-thaw. Compared with starch/dextrin formulations, the VAE system provides more consistent rheology at high maker speeds but may have higher cost and stricter pH control. Quality control of incoming JZ-I lots should include nonvolatile content by ISO 3251:2019, pH by ASTM E70-19, and Brookfield viscosity by ASTM D2196-20. A retained sample should be kept for 6 months under sealed conditions for traceability. The certificate of analysis should be compared against the purchase specification, and any deviation should trigger a process capability review for the affected cigarette maker. This is standard practice for waterborne cigarette adhesives; no additional JZ-I-specific quality control requirement is published here.
From a regulatory perspective, suitability for the JZ-I grade must be established in the final cigarette component. The VAE polymer may be evaluated under 21 CFR 175.105 for adhesives and 21 CFR 176.170 for paper and paperboard components; however, cigarette papers and filters fall within tobacco-product regulations that may impose additional boundary conditions. The formulation is not sold as a food-contact substance; compliance with EU 10/2011, REACH, or RoHS requires declaration and end-use testing on the final product. No JZ-I-specific regulatory outcome is published in this document.
The JZ-I VAE emulsion should be stored in sealed containers at 5 °C to 35 °C. Freeze-thaw cycling below 0 °C can cause irreversible viscosity increase and coagulum formation; a single freeze event may settle the emulsion even after rewarming. The emulsion is maintained in a weakly acidic pH range to suppress vinyl acetate hydrolysis. Strong alkali addition above pH 7.5 accelerates saponification and can generate acetic acid odour and destabilisation. Acid contamination below pH 3.0 can protonate the protective colloid and create grit. Aluminium, zinc, and copper fittings should be avoided because metal-ion contamination can produce coloured scale. Circulation systems must include a low-level interlock to prevent pump starvation and air entrainment, both of which increase coagulum formation. Published data for this specific JZ-I configuration is limited; storage stability curves should be generated at the intended plant temperature extremes. The product is not a hot melt; it must not be heated above the manufacturer’s limit.
