Packaging plays a particularly important role in product quality assurance, and there are a wide variety of materials used in packaging. Among them, due to its good mechanical properties, barrier properties, safety performance, and its superior processing performance,DOS oil coated aluminum foil sealing has good sealing performance, excellent freshness preservation and light shielding properties, which can prevent product oxidation and deterioration.The main advantages of aluminum foil sealing film are as follows:
1. It has a beautiful appearance and is close to the product, which can be applied to many types of packaging of different sizes.
2. Strong protection. If the inner packaging of the sealing film is connected with the transmission packaging hanging on the outer packaging, it can have excellent protection.
3. It is clean and hygienic, especially suitable for the use of precision instruments and high-precision electronic components.
4. It is of high quality and low price.
5. It is of high safety and pilfer proof.
The technical principle of aluminum foil sealing is to heat the aluminum foil sealing gasket through electromagnetic waves, so that the heat-sealing layer of the aluminum foil sealing gasket is heated and melted, and the heat-sealing layer and the bottle mouth are bonded under a certain pressure condition, so as to achieve a fast non-contact air seal
