Aluminum foil bag, also known as pure aluminum bag, is a bag made by a bag making machine after being combined by a variety of plastic films.
Most aluminum foil bags adopt four layer structure, which has good water and oxygen separation functions.
The products shall be tested according to GB and ASTM standards. The products meet the requirements of environmental protection (a third-party test report can be provided).
The products meet the most stringent environmental protection standards for packaging materials in EU and North America.
Plastic particle aluminum foil bag refers to the packaging made of plastic particles. Common plastic particles include general plastics, engineering plastics and special plastics.
Good performance, with the following characteristics: opaque, silvery white, anti gloss, good barrier, heat sealing, light shielding, high and low temperature resistance, oil resistance, fragrance retention, softness and so on.
Plastic particle aluminum foil bags are widely used in various industries.
1. Food packaging: aroma, quality, taste and color preservation of rice, meat products, dried fish, aquatic products, cured meat, roast duck, roast chicken, roast pig, quick-frozen food, ham, cured meat products, sausage, cooked meat products, pickles, bean paste, seasoning, etc.
2. Hardware and Electronics: applicable to the packaging of circuit boards, electronic products, mechanical accessories, consumer goods, industrial products, etc.
3. Pharmaceutical packaging: plastic particle aluminum foil bag is suitable for the packaging of large machinery and equipment, chemical raw materials, medicine, etc.
How to control the thickness of aluminum foil bag
1.the key to the thin and thick symmetry of the plastic particles aluminum foil bags is the thickness and symmetry of the compound front mask.
In other words, the thin quality of the aluminum foil bag is the prerequisite for achieving the quality of the manufactured goods manufactured goods.
2.The high barrier of aluminum foil bag plastic film is closely related to the thickness of vacuum bag plastic film.
3.Aluminum foil bag plastic film with good symmetry can obtain uniform and stable high barrier.
4.Plastic particles aluminum foil bag plastic film thickness uniformity endangers the mechanical equipment drawing characteristics of plastic film.
Aluminum foil bag plastic film with good thickness uniformity can obtain good packaging and printing precision and composite quality.
4. Similarly, for the plastic particle aluminum foil bag film of the inner material, the higher the thickness, the higher the starting and ending heat sealing temperature, and the opposite is true.
In other words, the thin and symmetrical aluminum foil bag film can obtain uniform nailing quality and prevent some potential safety hazards of heat sealing.
