In thermoformed water-soluble sachet production, EXCEVAL RS-1717 is dissolved in demineralized water at 80–85 °C under low-shear agitation to form a 25–35 wt% casting solution. The resin is handled as a partially hydrolyzed polyvinyl alcohol with a 4 wt% aqueous solution viscosity of 16.5–19.5 mPa·s at 20 °C per GB/T 12010.3-2010 and a hydrolysis degree of 92.0–94.0 mol% per JIS K6726. For automatic dishwasher and laundry unit-dose films, the formulation is adjusted to balance cold-water dissolution and mechanical integrity after thermoforming. A representative compound contains 68–82 wt% EXCEVAL RS-1717, 10–20 wt% plasticizer selected from glycerol or sorbitol, 0–12 wt% dextrin or oxidized starch, and 0.1–2.0 wt% surfactant or release agent. The casting line uses a slot die and a chilled steel belt maintained at 20–40 °C; the wet film is dried to 6–10 wt% residual moisture before winding. Thermoforming into unit-dose cavities is performed at 110–140 °C with heated plug assist and 0.4–0.8 MPa forming pressure. Film dissolution time in 20 °C water increases from 20–35 s at the high-plasticizer end to 60–90 s at the high-starch, low-moisture end, as measured by MSTM 205-adapted immersion testing. Tensile strength and elongation at break are evaluated under ASTM D882; tear resistance is checked according to ASTM D1922-09. Regulatory assessment for finished detergent units typically references Regulation (EC) No 648/2004 and ISO 14851 for inherent aerobic biodegradability in aqueous medium. Operational boundaries are material: films stored at relative humidity above 60% require pre-drying to below 8 wt% moisture before thermoforming; failure to do so produces cavity thinning and premature dissolution at the side wall. Film blocking has been observed after 12 weeks at 40 °C/75% RH unless a release sachet or desiccant barrier is used. Finished product types include automatic dishwasher detergent pouches, laundry liquid unit-dose packs, solid rinse aid sachets, and pre-portioned agrochemical water-soluble envelopes.
| Component | Low-temperature dissolution profile | Standard unit-dose profile | High-cavity-fill profile |

Size press operations on filled paperboard convert EXCEVAL RS-1717 into a 2.0–6.0 wt% aqueous solution at 60–70 °C and blend it with anionic or amphoteric starch at a starch-to-PVOH ratio between 95:5 and 80:20 on dry solids. The applied dry pick-up is typically 0.3–1.2 wt% of base sheet mass. Rod-metering size presses running at 400–1200 m/min require solution viscosity in the range 150–400 mPa·s at 60 °C, measured by Brookfield RVT spindle 4 at 20 rpm, to prevent rod streaking and sheet edge deposition. After impregnation, web drying at 100–140 °C to 4–6 wt% final moisture develops the film network that binds calcium carbonate and kaolin in the surface layer. Surface strength is verified by ISO 3783 IGT pick testing and water absorption by ISO 535 Cobb60. Food-contact suitability is assessed under FDA 21 CFR 176.170 and 176.180; mill handling is normally embedded within an ISO 22000 food safety management system. Processing limits appear when dry pick-up exceeds 1.2 wt%: water absorption increases and the sheet becomes prone to blocking in reel storage. Below 0.3 wt% dry pick-up, IGT surface strength improvement is less than 0.5 m/s relative to a starch-only control. Finished product types are folding carton board, coated linerboard, inkjet base paper, thermal base stock, and single-pass coated packaging papers.
Because EXCEVAL RS-1717 retains high aqueous viscosity at low dosing, vinyl acetate-ethylene emulsion polymerization reactors use it as the continuous-phase protective colloid in semi-continuous stirred-tank operation. The resin is pre-dissolved at 10–15 wt% in demineralized water at 90 °C for 4–6 h with 300 rpm anchor agitation; the solution is then metered into the reactor at 1.0–6.0 wt% of monomer mass, typically with 60% in the initial charge and 40% in the delayed feed. Polymerization is maintained at 60–85 °C and 0.5–3.0 MPa ethylene partial pressure using a redox system of hydrogen peroxide and sodium formaldehyde sulfoxylate or ammonium persulfate. Finished emulsion solids are typically 50–60 wt%, with Brookfield RVT viscosity between 2000–8000 mPa·s at 25 °C. Published data specific to RS-1717 in high-ethylene vinyl acetate configurations is limited; the above operating window reflects production-scale PVOH protective colloid practice rather than a supplier-guaranteed specification. The dispersion must be protected against polyvalent metal salts such as aluminum sulfate or calcium chloride above 0.05 wt%, which cause irreversible PVOH complexation and coagulum formation. Amine-based additives that raise the aqueous phase pH above 7.5 accelerate viscosity drift and must be avoided unless buffered with acetic acid to pH 4.0–5.5. Regulatory alignment for the resulting adhesives includes FDA 21 CFR 175.105 for indirect food-contact adhesives and EN 204/205 for classification of thermoplastic wood adhesives. Terminal product types fall into furniture and joinery PVA wood adhesives, laminating adhesives, carpet backcoating binders, and nonwoven saturation binders.
Slasher sizing machines running polyester and cotton warps at 700–1100 rpm on air-jet looms formulate EXCEVAL RS-1717 at 8–14 wt% dry solids in the size liquor. The size box is held at 85–95 °C; yarn pre-wetting at 60–70 °C is required for hydrophobic polyester to ensure size film adhesion. Squeeze roller pressure is set at 5–10 kN/m to target size add-on of 8–15 wt% on yarn mass. A typical blend is 20:80 to 50:50 PVOH-to-starch on dry solids, with wax lubricant at 0.3–1.0 wt%, antistatic agent at 0.1–0.3 wt%, and silicone defoamer at 0.05–0.2 wt%. The slasher drying canopy is profiled from 120–140 °C in the first zones to 100–110 °C in the final zone, with final yarn moisture regain controlled to 2–4%. Size film tensile strength and elongation are measured by ISO 527-3 on isolated film; yarn abrasion resistance is checked through weaving stop counts on the target loom configuration. Finished textile substrates are tested for restricted substances under Oeko-Tex Standard 100, GB 18401-2010, and ZDHC MRSL v3.1. Operational limitations include embrittlement of the size film when dry size solids exceed 14 wt% and ambient humidity drops below 45%; warps shed excessively and increase loom stop counts. Terminal product types include high-density polyester taffeta, cotton shirting, blended sheeting, and home textile upholstery fabrics.
Remoistenable adhesive coating operations in label and envelope converting deploy EXCEVAL RS-1717 as the water-activatable film former. The coating solution is prepared at 10–20 wt% solids in water, heated to 70–80 °C to dissolve, and then cooled to 35–45 °C for application. Typical dry coat weight on paper or film facestock is 3–8 g/m², applied by direct gravure or roller coater at 30–60 m/min. Formulation modifiers include 5–15 wt% plasticizer on PVOH and 10–30 wt% dextrin on PVOH; dextrin above 30 wt% slows remoistening tack development beyond 2–5 s and can produce paper curl. Drying is performed in a 70–110 °C forced-air tunnel to a final water content of 4–6 wt%. Adhesive bond development after remoistening is measured by ASTM D6195 loop tack adapted to a 35 s dwell on paper facestock. Regulatory alignment is through FDA 21 CFR 175.105 for indirect food-contact adhesives and EN 71-3 migration limits when converted into children’s paper craft articles. The operational boundary is the compatibility window with borate or glyoxal crosslinkers: adding above 0.2 wt% borate to the wet adhesive raises solution pH above 8.5 and causes gelation within 2–4 h. Terminal product types include envelope flaps, paper labels, spiral paper tube cores, and remoistenable stamp stock.
Aqueous ceramic slurry preparation with EXCEVAL RS-1717 begins with a 5–10 wt% PVOH solution that is added to a 40–60 wt% solids alumina, silica, or ferrite slurry to achieve 0.5–2.0 wt% dry binder on ceramic body mass. Ball mill mixing at 60–80 rpm for 2–4 h disperses the organic binder through the mineral phase; spray drying then operates at inlet 180–220 °C and outlet 90–110 °C to produce granules with 2–4 wt% residual moisture. Compaction is performed at 30–50 MPa uniaxial pressure to a green density of 1.8–2.1 g/cm³, with green flexural strength measured by ASTM C1161 three-point bending. Binder burnout is conducted between 400–600 °C for 1–2 h; residual ash must remain below 0.1 wt% for electronic ceramics and below 0.5 wt% for structural porcelain. The operational boundary is the shear sensitivity of the slurry: addition of PVOH above 2.0 wt% dry basis raises Bingham yield stress above 300 mPa·s at 100 s⁻¹ and impedes spray-dryer pump transfer. Finished product types include technical ceramic substrates, ferrite cores, oxide ceramic preforms, and porcelain tile bodies.

EXCEVAL RS-1717 is an ethylene-vinyl alcohol copolymer grade with a nominal ethylene content of 32 mol%, supplied as pellets for coextruded barrier layers in rigid sheet, blown film, cast film, and multilayer packaging structures. The grade is specified as an internal oxygen barrier layer rather than as a structural resin. Table 1 lists typical values obtained under standard laboratory conditioning; the values are not specification limits and should be verified against lot-specific certificates of analysis.
| Property | Test method | Typical value |
|---|---|---|
| Ethylene content | Internal method | 32 mol% |
| Melt flow rate at 190°C, 2160 g | ISO 1133-1:2022 | 1.7 g/10 min |
| Density at 23°C | ISO 1183-1:2019 | 1.17 g/cm³ |
| Melting temperature | ISO 11357-3 | 183°C |
| Glass transition temperature | ISO 11357-2 | 61°C |
| Oxygen permeation coefficient at 23°C, 0% RH | ASTM D3985 | 0.006 cm³·mm/m²·day·atm |
| Oxygen permeation coefficient at 23°C, 65% RH | ASTM D3985 | 0.4 cm³·mm/m²·day·atm |
Oxygen permeability in ethylene-vinyl alcohol copolymers is not a single material constant. The permeation coefficient increases with moisture uptake because water plasticises the hydroxyl-bearing amorphous regions. Between 0% RH and 85% RH, the oxygen permeation coefficient of a 32 mol% EVOH grade typically rises by one to two orders of magnitude. Consequently, the barrier performance of RS-1717 in a finished package must be evaluated in relation to moisture ingress through adjacent polyolefin skins and tie layers, not on the basis of dry-film laboratory values alone.
Microcracking in thermoformed barrier trays occurs when the EVOH layer is stretched below its practical forming temperature or beyond the draw ratio that the grade can accommodate without discontinuous thinning. With RS-1717, the 32 mol% ethylene content shifts the practical plug-assist thermoforming window to 120°C to 150°C for sheet thicknesses from 0.8 mm to 1.5 mm. On a production pressure former with clamp force of 80 t, upper and lower oven zone settings of 350°C, and a forming-cycle time of 4 s, the grade remains processable at draw ratios up to approximately 2.5:1. Trial data from a 1,250 mm wide multilayer die showed that edge bead above 10 mm produced barrier-layer thinning below 3 μm at the corner shoulder, resulting in elevated oxygen transmission when tested after thermoforming. This failure mode is distinct from thermal degradation and is controlled by adjusting die-lip profiles and edge bead temperatures rather than by increasing EVOH layer thickness alone.
Tie-resin selection controls interlayer adhesion in these structures. Maleic anhydride-functionalised polypropylene with a melt flow rate of 1.0 g/10 min to 3.0 g/10 min at 190°C is commonly combined with RS-1717 in PP-based trays. Heat-seal peel adhesion above 8 N/15 mm, tested according to ASTM F904, indicates adequate tie-layer bonding. When regrind content exceeds 20 wt% in the tie layer, adhesion can fall below 4 N/15 mm, producing intermittent delamination along trimmed tray flanges.
RS-1717 must be dried to 0.01% (100 ppm) moisture or lower before melt processing. Desiccant-bed drying at 80°C to 90°C for 4 h with a dew point of −40°C or lower is standard. Drying longer than 8 h at temperatures above 100°C may induce pellet yellowing and should be avoided. The recommended melt temperature measured at the die is 210°C to 240°C. Barrel zones above 250°C promote crosslinking and gel-particle formation. Maximum residence time from feed throat to die should not exceed 10 min at 240°C. Screw geometry is a processing boundary: single-flight polyolefin screws with L/D of 24:1 to 32:1 and a compression ratio of 3.0:1 to 3.5:1 are preferred. Avoid reverse-flow check rings with narrow clearances that can hold stagnant resin. Purging should be performed with medium-density polyethylene or high-density polyethylene. Polyvinyl chloride, acetal, and ionomer purging compounds are incompatible because acidic residues can catalyse cleavage of vinyl alcohol segments and generate gel particles.
Five-layer polypropylene sheet coextrusion lines typically place RS-1717 between two maleic anhydride-functionalised PP tie layers. The target barrier layer thickness is 5 μm to 15 μm. Below 5 μm, thickness variation across dies wider than 1,200 mm becomes a controlling risk for oxygen leakage at fold corners. Melt pumps with a capacity of 10 cm³/rev and speed variability below 0.1% are used to maintain layer uniformity. In cast-film lines running at 150 m/min, the internal barrier layer is quenched at 20°C on a chill roll. If the chill-roll surface temperature falls below the local dew point, condensation on the film edge can raise local moisture content and degrade the barrier layer before lamination.
In retortable structures subjected to 121°C for 30 min, replacing a 38 mol% EVOH with RS-1717 lowers dry-state oxygen ingress but increases sensitivity to moisture loading through the sealant. The oxygen permeation coefficient after conditioning at 23°C and 65% RH is approximately 0.4 cm³·mm/m²·day·atm for RS-1717, compared with a typical value nearer 0.9 cm³·mm/m²·day·atm for a common 38 mol% EVOH under the same test. However, after steam retort exposure, the coefficient of RS-1717 does not recover until the sealant layer has reduced its internal moisture load below 0.1%. In a structure using a 70 μm cast polypropylene sealant, recovery can require 7 days at 23°C and 50% RH. With a 150 μm sealant, recovery can extend beyond 14 days. This behaviour limits the use of RS-1717 in direct hot-water boil-in bags without a polyolefin moisture barrier. Published package-permeation data for this exact grade under high-humidity retort are limited; the coeffective values above are raw material coefficients rather than finished package transmission rates.
Table 2 compares typical oxygen permeation coefficients for RS-1717 with three alternative barrier polymers after equilibrium conditioning. The values are drawn from published laboratory film data and are not direct package permeability values. Layer structure, tie-resin compatibility, orientation, and heat history all change final package transmission rates.
| Material | 0% RH | 65% RH | 85% RH |
|---|---|---|---|
| EXCEVAL RS-1717 32 mol% EVOH | 0.005–0.02 | 0.3–0.6 | 1.5–4.0 |
| EVOH 38 mol% | 0.02–0.05 | 0.8–1.5 | 3.0–7.0 |
| Polyamide 6 | 8–15 | 18–35 | 30–50 |
| PVdC | 0.5–1.0 | 0.6–1.2 | 0.7–1.5 |
PVdC maintains a relatively flat barrier response over the same humidity range, but RS-1717 provides lower oxygen permeation at 0% RH by approximately two orders of magnitude. Polyamide 6 shows an oxygen transmission coefficient at 65% RH that can be 20× to 80× higher than RS-1717 depending on grade and crystallinity. This difference explains why an EVOH oxygen barrier layer in multilayer packaging is usually 5 μm to 15 μm thick, while an equivalent polyamide 6 oxygen barrier layer often requires a thickness above 100 μm.
Compared with a 27 mol% EVOH grade, RS-1717 exhibits a wider processing window and improved thermoformability because the higher ethylene content reduces the stiffness of the hydrogen-bonded network. Compared with a 38 mol% EVOH grade, it provides lower oxygen permeation under dry conditions but requires more aggressive moisture management in high-humidity service. Compared with PVdC, RS-1717 avoids chloride-related disposal concerns but loses barrier advantage above 60% RH unless it is fully enclosed by polyolefin moisture-shielding layers.
Food-contact compliance is established under FDA 21 CFR 177.1360 for ethylene-vinyl alcohol copolymers and under EU Regulation (EU) No 10/2011 when the final multilayer structure meets the applicable overall migration and specific migration limits for ethylene glycol and vinyl alcohol oligomers. REACH, RoHS, and California Proposition 65 obligations apply to the finished article, not to the resin alone, because migration behaviour depends on tie-resin coverage, alcohol content, and processing history. The grade is not recommended for direct contact with ethanol above 20% by volume because high alcohol solubility plasticises the barrier and can increase monomer migration beyond test limits.
In aseptic paperboard packaging, RS-1717 is inserted between polyolefin tie layers at 6 μm to 10 μm in laminated board structures. Extrusion lamination at 150°C to 180°C is below the degradation threshold, but incoming paperboard moisture content must be below 8%. Higher paperboard moisture generates steam at the polymer-paper interface, causing pinholing and local barrier failure. On pilot lines with a 600 mm slot die, the EVOH layer temperature at the nip was maintained at 170°C ± 5°C. Excursions above 180°C for more than 5 min produced gel particles larger than 200 μm, which were visible in the finished laminate as raised specks and represented local oxygen transmission defects.
