Custom pockets or restraints may be possible, but they are not confirmed options in the available specification for this bottom-gusset insulated bag. Before ordering, ask the manufacturer to assess your proposed layout and confirm which features can be added. Request a physical sample with the agreed design before approving production.
The bag is described as a bottom-gusset design without side gussets, finished with a four-edge seal. Its stated layers are an aluminium foil laminate outer face, a 2–5 mm closed-cell EPE foam core, and a food-grade PE contact layer. An air-bubble core can be requested. Base depth options are 8, 10, or 12 cm, and listed sizes range from 30 × 35 + 8 cm to 50 × 55 + 12 cm.
The standard opening is heat-sealed. A zip track or tear notch may be requested, and a moulded handle is welded into the top seal. The product information does not specify internal pockets or restraints, nor explain how they might affect the bag’s capacity, sealing, or insulation. Treat these as requirements to review, not features already included.
When requesting a design review, provide the bag dimensions, a description of the intended contents, the number and position of pockets, and the type and placement of restraints or fastenings. Include your preferred closure and any other access requirements. The manufacturer should confirm feasibility, construction details, and pricing for the requested additions.
Huizhou Ecopack Packaging Products Co., Ltd. reports that its in-house structural design and tooling team can prepare a 3D structural drawing for approval before printing plates are made. The company says sampling generally takes 3 to 5 working days. Review the finished physical sample carefully, including the interior layout, before authorizing production.
The company describes a pharmacy cold-chain application for 2–8°C shipments. That separate scenario uses an insulated bag or mailer with a dedicated sleeve for a phase-change gel pack, as well as a flat, unprinted window on the front panel for monitoring and batch labels. This description does not establish that the bag in this specification is validated for 2–8°C transport or qualified for a particular medical use.
If the bag will carry temperature-sensitive medical contents, request product-specific performance and testing information before relying on it. Confirm that the proposed compartments and restraints work with the contents and the intended shipping conditions.
| Design area | Details listed | Questions to resolve |
|---|---|---|
| Format | Bottom gusset, no side gussets, four-edge seal | Can the proposed pockets and restraints fit this format? |
| Materials | Aluminium foil laminate outer face, 2–5 mm closed-cell EPE foam core, food-grade PE contact layer | Will the materials and compartment arrangement suit the proposed contents? |
| Opening and handle | Heat-sealed mouth; zip track or tear notch on request; moulded handle welded into the top seal | Which closure is suitable, and will interior access require design changes? |
| Customization | Structure, size, base depth, core, print, and colour | Are pockets and restraints feasible, and what are their design and cost implications? |
| Sampling and production | Samples typically take 3 to 5 working days; production takes 15 to 25 days after artwork approval | Has the internal arrangement been checked on an approved physical sample? |
No. Neither feature appears in the supplied product details. Ask the manufacturer to confirm whether they can be incorporated into your requested design.
Send the required dimensions, intended contents, pocket count and positions, restraint or fastening requirements, and preferred closure. The manufacturer will need to confirm feasibility and final specifications.
No. The company describes a separate pharmacy cold-chain application, but the provided specification does not state a validated temperature range or medical-use qualification for this particular bag. Ask for product-specific confirmation and testing details.
The listed customization options cover features such as structure, dimensions, base depth, core, printing, and colour; pockets and restraints are not confirmed. Share your layout and use requirements with the manufacturer, obtain confirmation, and approve a physical sample before production. Custom orders typically begin at 5,000 to 10,000 pieces, depending on the specification. Sampling is generally 3 to 5 working days, while production is listed as 15 to 25 days after artwork approval.
