Aluminium Foil For Packaging
Aluminum foil is a packaging material that has not yet been replaced. It has many advantages such as non-toxicity, thermal conductivity, shading, moisture barrier, fragrance preservation, etc., so it is widely used. However, in practical application of aluminum foil, there are still a lot of attention. Therefore, Shunxingyuan Packaging, a professional manufacturer of flexible packaging, specially organized it for you.
Application of aluminum foil
Aluminum foil is mostly used for high-grade packaging and blister packaging of cosmetics, mildew-proof and moisture-proof packaging for clothing and apparel, moisture-proof and fragrance-preserving paper for cigarettes, high-grade packaging for chocolate, anti-leakage packaging for daily chemical products, sealing film for instant noodle bowls, beer And champagne sealing labels, milk and dairy products and multi-packaging of fruit juices, etc.
Aluminium foil is rarely used alone
Aluminum foil is widely used in flexible packaging. Due to its low strength, it is easy to break at the beginning of folding. So it is rarely used alone.
Generally, it is made into composite packaging materials with paper, cellophane and polyethylene film. When compounding, according to different types of adhesives, adhesive bonding, dry compounding, extrusion compounding, casting compounding, etc. are used to make up for its easy rupture and lack of Disadvantages such as flexibility, no thermal adhesive, etc. When aluminum foil is composited with other materials, the air tightness and moisture resistance of other materials should be considered. The composite of aluminum foil and polyester film can greatly improve the folding resistance.
The thickness of aluminum foil should be considered in composite use
The thickness of aluminum foil used in composite materials can be 0.007~0.009mm, which is also more economical. At present, thinner aluminum foil has five to six hundred perforations per square meter, and if its necessary strength is neglected, it can only be moisture-proof. If its thickness is more than 20μm, it can meet the requirements of no holes and moisture resistance.
In actual use, in addition to packaging food and medicine, the thickness selection should be based on different contents.
Aluminum foil features
1. The surface of the aluminum foil is extremely clean and hygienic, and no bacteria or microorganisms can grow on its surface.
2. Aluminum foil is a non-toxic packaging material, which can be in direct contact with food and will not harm human health.
3. Aluminum foil is an odorless and odorless packaging material, which will not make the packaged food have any peculiar smell.
4. If the aluminum foil itself is not volatile, it and the packaged food will never dry or shrink.
5. No matter in high temperature or low temperature, the aluminum foil will not have the phenomenon of grease penetration.
6. Aluminum foil is an opaque packaging material, which is a good packaging material for products exposed to sunlight, such as margarine.
7. Aluminum foil has good plasticity and can be used to package products of various shapes, and can also be arbitrarily formed into containers of various shapes.
8. The aluminum foil has an elegant silver-white luster, and it is easy to process beautiful patterns and patterns of various colors.
In short, aluminum foil is a soft metal film with the advantages of moisture resistance, air tightness, shading, abrasion resistance, fragrance preservation, non-toxic and tasteless, etc., so it is favored by people and has become the darling of today's packaging market.
