Sealng method:
The ziplock bag is usually sealed by pressing or pressing the bag mouth so that the sticky material on the back is bonded together to form a seal.
The self-adhesive bag is sealed by folding the bag mouth in half or gently pressing it so that the adhesive layer of the bag mouth and the bag body are bonded together to form a seal.
The main purpose:
Ziplock bags are usually used for packaging lightweight items, such as nuts, trinkets, small hardware, small toys, snacks, tea, etc.
Self-adhesive bags are usually used for the packaging of larger items or heavy items,
such as clothing, books, food, cosmetics, etc. They are usually more suitable for use in express delivery and transportation.
Advantages and features:
The ziplock bag is convenient, fast and easy to use. It is easy to seal and does not require other auxiliary tools and can be reused.
Self-adhesive bags provide a stronger seal and durability for items that require greater protection,
and the adhesive layer often bonds more firmly to prevent the possibility of disassembly.
In general, although both ziplock bags and self-adhesive bags are suitable for packaging and sealing,
their uses and characteristics are slightly different, so the specific packaging needs and item characteristics need to be considered when choosing.
Self-sealing bag: There is a sealing line at the mouth of the bag. Align the lines on both sides of the mouth of the bag,
press it to seal, and pull it open to open the bag. It does not use glue and can be used repeatedly.
Self-adhesive bag: There is a piece of glue at the mouth of the bag. When you buy it, you cover it with a small piece of plastic paper. When you need to seal it,
tear off the plastic piece to expose the glue, and then you can seal the bag. It is generally a one-time packaging product.
Self-sealing bags refer to packaging bags that can be automatically sealed by pressing.
