Flat Pouches and Flat Bags are both flat bags used for packaging, but there are some differences in design, usage scenarios and functions.
Contents
Flat Pouch
Features
Structure: Usually a sealed flat packaging bag, generally using heat-sealed, zippered, or self-sealed designs. The top or side can be opened, and usually designed with a reseal function (such as a zipper) for multiple uses.
Material: Usually a more durable multi-layer material is used, which may be composite plastic, aluminum foil, or other pressure-resistant and moisture-resistant materials with good barrier properties.
Function: Due to its good sealing performance, it is often used for packaging of products such as food, cosmetics, and small items, providing strong protection and maintaining the freshness of the product.
Common Applications
- Food packaging (such as snacks, coffee, dry goods, etc.)
- Cosmetics (such as facial masks, sample packs)
- Medical products
Flat Bag
Features
Structure: Usually a simple flat bag with an opening, no sealing design (such as self-sealing or zipper) at the opening, and requires external tools (such as heat sealers or straps) to seal.
Material: It can be ordinary plastic, paper, or textiles, and is common in simpler and lighter packaging applications. The material is usually thin and light, and does not necessarily have strong barrier properties.
Function: Usually used for temporary or short-term packaging, suitable for simple goods, or as a one-time packaging.
Common applications
- Disposable shopping bags
- Product packaging bags (such as clothing, stationery)
- Industrial packaging bags (such as hardware parts packaging)
Main differences
Sealing method
Flat Pouch: Usually has a resealable zipper or self-sealing structure, or a heat-sealed packaging bag, suitable for multiple uses or long-term storage.
Flat Bag: Usually has no reseal function, the opening part needs to be manually closed, or it is a one-time use.
Materials and functions
Flat Pouch: Mostly used for packaging that requires higher protection, such as food or cosmetics, the material has the ability to block air, moisture, etc.
Flat Bag: Suitable for loading simpler goods, the material is relatively thin and light, and the protection is low.
Usage scenarios
Flat Pouch: More suitable for scenarios that require better sealing and protection, such as food preservation.
Flat Bag: Mostly used for packaging and transporting simple goods, such as shopping bags, clothing bags, etc.
Flat Pouches emphasize sealing, protection and multiple uses, and are suitable for items that need long-term protection.
Flat Bags focus more on simple packaging and one-time use, and are suitable for packaging daily goods.
