Aluminum Foil Soft Package 1235 7Micron Thickness
(1)Single-layer films are required to be transparent, non-toxic, impermeable, and have good heat-sealable bag making properties, heat and cold resistance, mechanical strength, grease resistance, chemical resistance, and anti-blocking properties. It can be produced by various methods such as extrusion blown film method, extrusion casting method, calendering method and solvent casting method. The heat-seal performance of a single-layer film is not only related to the molecular weight distribution and molecularization degree of the resin, but also related to the process conditions during film formation, such as temperature, cooling rate, and expansion ratio.(2)Aluminum foil is an ideal substrate for flexible plastic packaging. It has good gas barrier properties, water vapor barrier properties, light-shielding properties, thermal conductivity, and shielding properties. Aluminum foil over 25.4 inches has no pinholes and has good impermeability.
(3) Vacuum evaporation of aluminum film
Under high vacuum, the metal with low boiling point, such as aluminum, is melted and vaporized and deposited on the plastic film on the cooling roll to form an aluminized film with good metallic luster. The thickness of aluminum plating is 400-600m, which can greatly improve the oxygen barrier and moisture barrier of the substrate. The substrate should be corona treated and coated with sol.
(4) Aseptic packaging film
Mainly used in the production of food and pharmaceutical aseptic packaging, it requires: sterilization resistance; high barrier and strength; heat and cold resistance (not brittle at -20°C);
(5) High-temperature cooking pouches In the 1960s, the US Naval Research Institute first developed foods for aerospace applications. After that, Japan quickly promoted them and developed various new convenience foods for aerospace applications. The packaged food is sterilized by high temperature, and the shelf life is up to one year. And there are various types of packaging bags: stand-up bags, tray-shaped, dish-shaped, cup-shaped, and cylindrical shapes, which are quite popular among consumers. High temperature cooking bags can be divided into transparent type (shelf life of more than one year) and non-transparent type (shelf life of more than two years), high barrier type and ordinary type. According to the sterilization temperature, it is divided into low-temperature cooking bags (100°C, 30min), medium-temperature cooking bags (121°C, 30min), and high-temperature cooking bags (135°C, 30min).
The main advantages of high-temperature cooking bags: ①High-temperature cooking can kill all bacteria, 121℃/30min can kill all botulinum; ②Can be stored for a long time at room temperature, without refrigeration, can be eaten cold or warm; ③The packaging materials are good Barrier, no less than canned food; ④ Reverse printing, beautiful printing; ⑤The waste is easy to incinerate.
