Eco Friendly Aluminum foil from HTMM for Flexible Packaging
Production General Information
The first category: food and drug packaging. It is mainly sealed, which mainly emphasizes gas barrier, light barrier, and non-toxicity. This type of aluminum foil includes: pharmaceuticals, quasi-drugs (medical devices, medical supplies) packaging, thickness of 0.02mm, 0.015mm, 0.09mm, 0.007mm. Food, quasi food (toothpaste) packaging, 0.015mm, 0.012mm, 0.09mm, 0.007mm.
The second category: decoration. Mainly aesthetics, mainly emphasizing uniform surface gloss. This type of aluminum foil includes: various printing outer packaging, advertising, etc.
The third category is between the first and second categories, which requires both a certain degree of tightness and a certain degree of aesthetics. Mainly the outer packaging of cigarettes, wine and food. The main technical indicators of different aluminum foils Different aluminum foils require different characteristics.
Mechanical performance requirements are one of the characteristics of this type of aluminum foil. Because this type of aluminum foil is deformed by hot pressing, proper plasticity becomes very important. Otherwise, it is easy to crack during hot pressing. Similarly, this type of aluminum foil is not easy to be too thin, and the thickness is generally greater than 0.007mm. Too thin and easy to crack.
Non-toxic and pollution-free is one of the main requirements of aluminum foil, the surface is clean and free of oil, and the aluminum foil composition meets the requirements of food packaging standards. At present, the flexible packaging aluminum foil mainly uses industrial pure aluminum series such as 1235,1145,1100.
It is required that the rolling oil and related media used to produce this aluminum foil must not be toxic, meet food-grade hygiene standards, and have surface tension that meets the requirements to ensure composite bonding strength.
