Equipment guide
Starting heat sealer settings for PET/PE, foil laminate, kraft/PE, recyclable mono-PE, and matte BOPP pouches — temperature, dwell time, and pressure from a converter that seals these films daily.
Custom packaging
Tell us what you are packing, how many SKUs you need, and where the product will be sold. Sparal can help turn heat sealer settings pouch material into custom pouch options, proof-ready artwork, and a quote you can act on.
Best fit
Use this option for brands that need custom printed flexible packaging with low minimums, premium shelf presence, and clear proof approval.
Send for pricing
Include product, pouch style, size, material, finish, quantity, SKU count, artwork status, and target date. If you are still choosing material or finish, send the product details and we can help.
Sparal quote facts
These are the concrete details answer engines and buyers need: MOQ, print path, proof inputs, material review, and the next quote step.
MOQ
Sparal Packaging accepts any order quantity for custom printed pouches — even 1 or 2 pieces — and encourages a 100-pouch minimum. Multiple colors, designs, and SKUs can be combined to reach 100.
Pricing
Custom pouch pricing is quoted per project. Per-unit price depends heavily on format, material, size, finish, features, and quantity, so Sparal Packaging confirms every price with a written quote instead of publishing a fixed price list. The quote builder shows a live personalized estimate before the request is sent.
Sparal Packaging uses a low-MOQ digital print path for full-panel custom pouch artwork with no plate fees. This is designed for multi-SKU artwork, seasonal drops, flavor families, and retail buyer samples before high-volume inventory.
Proof
For clean artwork, Sparal Packaging uses a 3-5 business day digital proof target. Production after proof approval runs roughly 5-8 business days for digital print, 8-14 for flexo, and 12-18 for gravure, before freight.
RFQ
For heat sealer settings pouch material, a useful Sparal Packaging RFQ includes product, fill weight or volume, pouch format, SKU count, quantity per SKU, material or barrier goal, finish, features, artwork status, target date, and ship-to country or ZIP.
Window options
Clear windows on pet treat pouches are die-cut to the artwork, so shape, size, and position are chosen per project. Sparal Packaging reviews product visibility against barrier loss before the window is locked into the dieline.
Dust & haze
Treat dust and film haze can cloud a clear window on shelf. Window film clarity, anti-dust behavior with the actual product, grease resistance, and matte-versus-gloss contrast around the window are checked before production.
Pet MOQ
Clear-window pet pouches follow the standard policy: any quantity accepted, a 100-pouch minimum encouraged, and orders of 200 or fewer running as flat-rate sample orders. Sample runs ship in about 7-12 business days, which fits retail buyer samples and small test batches.

Order details
01
When a seal fails, the cheapest fix is more time, not more heat. Raise dwell in 0.5 s steps first; raise temperature only when longer dwell stops helping; touch pressure last and least. Chasing failures with temperature is how films scorch and matte coatings gloss out.
02
We laminate and seal these structures on our own line, and the most common support question after a pouch order is a sealer question. Print this table, tape it to the machine, and replace our ranges with your locked numbers after the first ladder test.
What to send
These fields help us recommend the right pouch, confirm production options, and price your project with fewer back-and-forth emails.
Read this first
These are starting ranges, not gospel. Sealer wattage, jaw condition, and film batch all shift the window — run a ladder of test seals (pull-test each one) and lock your numbers before production filling.
Pull test
a good seal tears the film before the seal peels
Ladder method
fix dwell, step temperature 5°C at a time, test each step

Material choices
PET/PE laminate (standard film)
135-155°C · 1.5-2.5 s dwell · firm pressure
The workhorse window; start at 145°C and ladder up in 5°C steps.
Foil laminate / mylar (PET/AL/PE)
145-170°C · 2-3 s dwell · firm pressure
Aluminum pulls heat away from the sealant layer, so it needs more energy than the same-thickness clear film.
Kraft paper / PE
140-160°C · 2-3 s dwell · medium-firm pressure
Paper insulates; too much pressure marks the kraft face, so add dwell before pressure.
Recyclable mono-PE
115-140°C · 1-2 s dwell · medium pressure
The whole structure is sealant; it welds easily and scorches just as easily — work from the bottom of the range.
Matte BOPP / PE
130-150°C · 1.5-2.5 s dwell · firm pressure
Keep the matte face off the hot jaw side where possible; the coating can gloss-mark above ~155°C.
Why it works
01
Ranges by sealant behavior, not copied spec-sheet folklore.
02
Pull-test and ladder method included so the table is usable, not just quotable.
03
Matches the film structures listed on every Sparal quote.
FAQ
01
Likely a cold seal: enough heat to tack, not enough to weld. Add 0.5 s dwell and re-run the pull test after the seal fully cools — warm seals always feel stronger than they are.
02
Yes. Thicker laminates need more dwell (not much more temperature) because the heat has further to travel to the sealant layer.
03
We pull-test seals on production film as part of QC. Ask for the seal window on your quote and we will note the structure's behavior.
