TL;DR: The most common reason an edible or water-soluble packaging brief goes through three rounds of revision is not design — it’s missing dissolution parameters and food-contact declaration at the first submission.
TL;DR: Across briefs we’ve received in the past 18 months, over 60% of requotes on water-soluble pouches were triggered by undeclared fill content weight or temperature constraints — both of which change film grade, seal spec, and tooling cost.
What We Need From You Before We Can Build a Quote #
A quotation for edible or water-soluble packaging is not a commodity price lookup. The film grade, seal bar temperature, pouch geometry, and compliance path all interlock — and each one affects unit cost in a different direction.
Here’s what we need at brief stage, in order of weight:
Fill content type and weight. Tell us what goes inside: a dry powder, a liquid detergent dose, a flavored gel, or a solid edible wafer. The answer changes everything. A PVA pouch for a unit-dose laundry pod uses a different PVOH resin grade and a different seal temperature window than a cold-dissolution sachet for a beverage powder. We also need the fill weight in grams — not a range, a target. A 10g fill and a 18g fill do not share the same minimum seal width spec.
Target dissolution profile. Cold water (below 20°C), warm water (30–40°C), or hot water (above 60°C)? We specify film thickness based on this. For cold-water dissolution, we typically use 25–30μm PVOH film. Warm-water applications allow 35–40μm for better mechanical durability during filling and handling. If you leave this blank, we’ll default to 35μm warm-water grade — and if your downstream process requires cold dissolution, that’s a full material change after sampling.
Regulatory pathway. Is this product food-contact, direct-ingestion (edible film), or non-food (e.g., agrochemical or laundry dose)? That determines whether we apply FDA 21 CFR §177.1670 (for polyvinyl alcohol in food contact), EU Regulation 10/2011 (for plastic food contact materials), or a different compliance tier. Non-food applications have more formulation latitude; food-contact and edible applications require ingredient-level sign-off on film stock, colorants, and any adhesive used in lamination.
Pouch dimensions and structural format. Provide finished pouch size (length × width in mm), desired film layers (single or multi-compartment), and whether you need a water-soluble secondary film over a non-soluble outer, or full dissolution of the entire package. For multi-compartment pods — which we run on our Form-Fill-Seal line at up to 120 units/min — the die geometry and compartment volume tolerance need to be confirmed at sample stage, not after.
Quantity tiers. We quote in three bands: trial (5,000–20,000 units), standard (50,000–200,000 units), and contract (500,000+ units/year). Tooling cost is amortized differently at each tier. For edible packaging formats like rice paper sleeves or seaweed wraps, our practical MOQ starts at 10,000 units due to substrate handling constraints during printing.
| Information Type | Why It Affects the Quote | If Missing |
|---|---|---|
| Fill content type & weight | Determines film grade, seal temp, and pouch geometry | We assume dry powder, may requote after sample |
| Dissolution temperature target | Drives film thickness selection (25–40μm range) | Default to warm-water grade; cold-water needs resample |
| Regulatory pathway (food/non-food) | Changes film resin spec and compliance documentation | Cannot confirm compliance cost until declared |
| Finished pouch dimensions | Required for tooling and FFS line setup | Estimated tooling cost only — firm price after approval |
| Print artwork (AI/PDF, 300 dpi min) | Needed for ink type selection (water-based or food-safe UV) | White sample only; printed proof delayed 5–7 working days |
Where Briefs Break Down — and What It Costs You in Time #
The single most time-consuming failure mode we see is a brief that specifies the aesthetic outcome without specifying the functional requirement. A brand submits artwork, selects a “natural look” edible rice paper, and asks for a sample — but hasn’t told us whether the package needs to survive 85% RH storage for 6 months or whether it will be consumed within 2 weeks. Those are not the same product.
For water-soluble pouches, the second common failure is conflating “water-soluble” with “immediately dissolving.” PVOH film at 35μm in 20°C water has a dissolution onset of roughly 60–90 seconds under agitation. Without agitation, it can take 4–6 minutes. If your product brief says “dissolves in 30 seconds,” that is a customer expectation problem, not a film spec problem — but we need to flag it before sealing samples, not after a consumer complaint. Our internal product intake form (we call it the SR-01 brief template) specifically asks for expected end-user dissolution condition so we catch this upstream.
Artwork files are a smaller but consistently recurring issue. We receive low-resolution JPEGs submitted as “final artwork” roughly once every two to three weeks. For water-soluble film printing, we run flexographic and digital inkjet depending on run length and substrate porosity. Both require vector or high-resolution raster files (minimum 300 dpi at finished size, ideally 600 dpi for fine-line detail). Bleed must be set to 3mm minimum. Color profiles should be submitted in CMYK; we convert to our press profile internally, but submitting in RGB adds a proofing round. Any Pantone references should be declared in the file — we match to Pantone Solid Coated standards and report ΔE against target at proof stage (our acceptance threshold is ΔE ≤ 2.0 on food-contact printed surfaces).
One scenario that causes requotes rather than just delays: a buyer submits a brief for a 3-compartment water-soluble pod with a total volume of 22ml, but the artwork shows design elements that require printing across the compartment seam lines. We cannot print continuous graphics across a live seal line on our current FFS tooling setup. If that’s a hard brand requirement, it changes the die design, the print registration spec, and adds roughly 8–12 working days to the sample timeline.
Is a White Sample Worth Requesting Before Final Artwork Is Ready? #
Yes — for water-soluble and edible formats specifically, a white sample (unprinted, correct dimensions and material) is worth requesting before your artwork is finalized.
The reason is that dissolution behavior, seal integrity, and hand-feel all need to be validated against the actual film grade before you commit print budget. A white sample lets your product team confirm the dissolution profile in real use conditions, verify that fill content doesn’t migrate through the film during the shelf life window, and check that pouch geometry works for your filling process. Our standard white sample lead time is 10–15 working days from brief confirmation. Printed proofs follow at 5–7 additional working days once artwork is approved. Production samples from the full-run tooling take 20–25 working days. These windows assume no material sourcing delays — for specialty edible substrates like seaweed-based film, add 7–10 working days for incoming material QC against ASTM F2475 water vapor transmission test criteria.
Specification Notes for Brand Partners #
When you brief us on edible or water-soluble packaging, the two pieces of information that most directly affect quote accuracy are fill content weight and dissolution temperature target. Without both confirmed, we can only provide a range quote with a material assumption caveat — which typically means a requote after sample review.
The most common gap we see in incoming briefs is missing food-contact compliance declaration. If your product is for direct human consumption or food-adjacent use, declare this upfront. It affects film resin selection, ink system, and the compliance documentation we prepare for your import market (FDA, EU, or GB standard). Retrofitting compliance documentation after sampling adds cost and timeline.
For brands shipping to the EU market, note that PVOH used in food contact applications must conform to EU Regulation 10/2011, which restricts specific migration limits (SML) for monomers. We can provide third-party migration test reports for EU-bound production runs, but that test lead time is 15–20 working days and needs to be scoped into your project plan.
Our SR-01 brief template is available on request — submitting a completed SR-01 reduces our sample preparation time by approximately one iteration cycle, typically saving 8–10 working days on first-sample approval.
Frequently Asked Questions #
How do I compare quotes fairly when two suppliers specify different film thicknesses?
It depends on your dissolution requirement and fill type. A 25μm film at a lower unit price might look better on paper — but if your fill is a hygroscopic powder and your storage condition reaches 75% RH, that thinner film may fail moisture barrier requirements before it reaches the shelf. Ask each supplier to confirm the film grade designation, the dissolution onset time at your target water temperature, and whether the quote includes compliance documentation. Price per unit is only comparable when the material spec and compliance scope are the same.
What artwork file format should I send?
Send AI or PDF with all fonts outlined, CMYK color mode, 300 dpi minimum at finished size, and 3mm bleed on all edges. If you have Pantone references, list them in the file — we’ll verify color match at ΔE ≤ 2.0 against Pantone Solid Coated during proof review.
Can you match a sample we already have from another supplier?
Yes, with caveats. Send us the physical sample and, if available, the material spec sheet. We’ll identify the film grade, measure caliper thickness, and run a dissolution test under ISO 15023-2 conditions to establish a baseline. We can reverse-engineer the structural spec in most cases, but if the original film is a proprietary resin formulation not available through our qualified supplier list, we will propose the closest equivalent and flag the difference explicitly before sampling begins.

The dissolution temperature point hit hard — we had a private-label tea brand submit a brief last year for a 6g single-serve sachet, left the dissolution field blank, and we sampled at 35μm warm-water grade. Their downstream process was a cold-brew application, sub-18°C, and the pouches were still intact after 8 minutes in consumer testing. Full material change to 25μm, new seal bar calibration, and a six-week delay to requalify the line. They’d actually noted “cold brew” in the product description on page one of the brief — we just didn’t have a mandatory field forcing the temperature declaration, so it got missed on both sides.
The cold-water vs. warm-water film grade split catches a lot of teams off guard on first orders — going from 35μm to 25μm PVOH for cold dissolution added roughly $0.09/unit for us at 50k MOQ, which doesn’t sound like much until your subscription box has four sachets per kit.
