Polypropylene/Aluminum/Polyethylene Composite Film BOPP - AL- LDPE

Polypropylene/Aluminum/Polyethylene Composite Film BOPP - AL- LDPE

Polypropylene/aluminum/polyethylene composite film has excellent barrier properties, strength and sealing. On the one hand, it can protect products from being corroded by light, moisture and oxygen, greatly extending the shelf life of goods; on the other hand, its stable nature also prevents it from being corroded by the product itself, and even products with certain corrosiveness can be packaged. It is mainly used for pharmaceutical packaging.
