BOPP/AL/PA/PE Composite Aluminum Foil Square-Bottomed Bag

Long - term Preservation: The combination of multiple materials endows the bag with excellent barrier properties, which can effectively extend the shelf life of products by preventing oxidation, moisture absorption, and microbial contamination.

Good Physical Protection: With high strength, puncture - resistance, and tear - resistance, it can protect products from physical damage during handling, storage, and transportation.

Versatile Packaging: It can be used for packaging various forms of products, such as powders, granules, solids, and semi - solids.

Printability: PET on the outer layer allows for high - quality printing, which is beneficial for brand promotion and product information presentation.

Heat - Sealable: The PE inner layer enables easy heat - sealing, ensuring good airtightness of the bag.

Antistatic (Optional): It can be designed to have antistatic properties, which is especially important for packaging sensitive electronic products and flammable and explosive chemicals.

Moisture - proof, Oxygen - proof, and Light - proof: Thanks to the aluminum foil layer, it can effectively block moisture, oxygen, and light, creating a stable storage environment for products.

Chemical - resistant: It can resist the corrosion of most chemicals, suitable for packaging chemical products.

High - temperature and Low - temperature Resistance: It can maintain its performance under certain high - temperature (such as for cooked food packaging) and low - temperature (such as for frozen food packaging) conditions.

Pharmaceutical Intermediates: Its high - barrier properties can prevent the contact between drug components and the external environment, ensuring the purity and stability of drugs.

Chemical Products: Such as pesticides and fertilizers. Its corrosion - resistance and chemical - solvent - resistance make it suitable for packaging corrosive or volatile chemical products.

Industrial Parts: For heavy - duty industrial parts like bearings and gears, it can provide sufficient support and protection during packaging.
