Insulated Zipper Pouch Styles and Closures

Zipper and Reclosable Track Seal Options

Both closure styles allow you to reopen the pouch to access the contents. Use a sample to check how the closure engages, how wide the opening is and whether you can close the pouch easily once loaded.

Flat and Bottom-Gusset Styles

The catalog lists flat and bottom-gusset styles. For thicker items, test a gusseted pouch to see how its expanded base fits the contents. Confirm both the bottom style and closure before placing a bulk order.

Materials, Construction and Thickness

Metallized Film, EPE Foam and PE Film

The pouch combines metallized PET film (MPET), expanded polyethylene (EPE) foam and PE film. The EPE foam forms the insulation layer in the pouch wall. Check the material construction and flexibility on a sample of your selected style.

Thickness Specifications and Measurement

The catalog lists a reference thickness of 1–2 mm. When comparing specifications or quotes, confirm whether the measurement applies to the foam layer or the finished laminate. Use the approved sample and specification to check the measurement.

Insulated Pouch Sizes and Fit

External Dimensions, Usable Opening and Interior Space

Checking Fit and Allowing Room for Closure

Measure the length, width and thickness of the item in its primary packaging. Check how much space the sealed edges take up and leave room at the top to close the pouch. If you plan to use a refrigerant pack, include it in the same fit check.

Applications and Packing Instructions

Carrying Prepackaged Small Items on Short Trips

For prepackaged small items that need protection from temperature changes on short trips, use a representative load to check the pouch fit and thermal performance. If the contents have a temperature requirement, test the packed pouch under your expected delivery or carrying conditions.

Loading and Closing the Pouch

Open the pouch and place the packaged item inside. Leave enough room at the top to close it without the contents pressing against the closure. Close the zipper or track seal as shown on the selected sample and check that it engages across the full opening.

Custom Printing, Samples and Bulk Orders

Artwork and Print Placement

Custom printing is available. Share your logo or artwork, preferred print placement and colors. Check how the print sits relative to the closure, sealed edges and gusset on the sample before approving the bulk order.

Loop Attachment and Sample Fit Checks

The catalog shows a sample with a short loop attachment. If you need this accessory, confirm its configuration, attachment point and intended use for the selected style. Use a sample to check the usable opening, closure, fit and print placement. Request a Sample

MOQ, Lead Time and Carton Packing

Confirm minimum order quantity and production lead time for your pouch style, dimensions, closure, printing and order quantity. Ask for the units per carton, carton dimensions and gross weight if you need them for storage or freight planning.

Insulated Zipper Pouches FAQ

How Do I Choose Between a Zipper and a Reclosable Track Seal?

Test each closure with the actual packaged item. Compare the opening width, ease of loading and closing, and how it feels if you need to reopen it during use.

Which Bottom Style Fits My Product?

Check the base dimensions and thickness of your packaged item. A bottom gusset folds out at the base, so use a sample to confirm the space and bottom style you need.

How Do I Choose the Right Pouch Size?

Provide the packaged item's length, width and thickness. Check the usable opening, interior space and room needed to close the pouch.

How Is Pouch Thickness Specified?

The catalog lists a reference of 1–2 mm. Ask which part of the pouch is measured and how, then check the approved sample against the specification.

How Long Can the Pouch Keep Contents Warm or Cold?

Performance depends on starting temperature, ambient conditions, loading and any refrigerant used. Test the complete packed pouch under your expected conditions.

Do I Need a Gel Pack for Chilled Items?

Decide based on the target temperature, surroundings and expected time in transit. If you use a gel pack, include it in both the fit check and the temperature test.

Can Food Go Directly Inside the Pouch?

Place food in suitable primary packaging before loading it into the pouch. For direct food contact, confirm the material documentation and intended use for the selected style before ordering.

Can I Customize the Printing and Loop Attachment?

Custom printing is available. Loop-attachment options depend on the selected style. Confirm the artwork placement and accessory attachment on the approved sample.

Can I Request a Sample Before Placing a Bulk Order?

Yes. Request a sample to check fit, closure and print placement. Sample type, charges and preparation time depend on the project.

How Are MOQ and Lead Time Confirmed?

Share the pouch size, bottom style, closure, artwork requirements and quantity. KENT can confirm the MOQ, lead time and carton packing for your order.
