Custom Four Side Seal Pouches FAQs
A: No. This page refers to a flat pouch with sealed edges around all four sides. It is not primarily a gusseted, three-dimensional pouch.
Quad seal bags commonly refers to gusseted bags with seals along four corners or edges. Terminology can vary between overseas suppliers, so a sample image or structural drawing should be included with the enquiry.
A: A finished four side seal bag has seals around all four edges. A three side seal pouch may use a folded edge and normally includes an opening for filling when supplied.
The pouch type should not be identified only by counting the sealed edges after final closure. The structural drawing, edge seals and supply condition should also be checked. Final sealing performance is validated according to the project.
A: Four-side sealing describes the final packaging state. It does not mean that an empty premade pouch is delivered completely closed.
For premade pouches, a filling opening must be agreed upon before the customer completes the final seal. If the pouch is formed, filled and sealed from rollstock, the film specifications and equipment requirements must be confirmed.
A: They can be evaluated for these applications, but sealed edges alone do not guarantee liquid leak resistance.
Please provide the formulation, fill volume, filling temperature and storage conditions. Contact materials, edge seals and final heat-sealing requirements must be confirmed, followed by compatibility and package-integrity validation for the intended use.
A: The outer dimensions should be evaluated together with the target fill volume, seal width and filling space.
Branded graphics, instructions and opening positions must remain clear of the sealed and cutting areas. Samples should be used to check filling, artwork placement and the tear notch before production specifications are finalized.
A: The MOQ and lead time depend on the materials, dimensions, number of designs and sealing requirements. Sampling, plate preparation, volume production and shipping schedules are confirmed separately.
For food or personal care projects, please provide the target market and document requirements. Applicable contact-material and testing information can then be confirmed according to the actual supplied structure.
