How To Tell Whether The Moisture Resistance Of Aluminum Foil Bags Is Up To Standard

We all know that aluminum foil packaging bags are widely used, aluminum foil packaging bags are usually suitable for large precision mechanical equipment, chemical raw materials, pharmaceutical intermediates moisture-proof, light-proof, vacuum packaging. The four-layer structure is mainly used, with good water and oxygen insulation. Unrestricted, can be customized with different specifications, styles of anti-static packaging bags, such as flat pocket, three-dimensional bag, organ bag, self-sealing pocket, zipper bag, self-adhesive bag, envelope pocket and other styles. Generally, the products of aluminum foil bag manufacturers are tested according to GB and ASTM standards, which meet the requirements of environmental protection (third-party testing reports can also be provided), and the products meet the environmental protection standards of packaging materials in the European Union and North America.

How about the moisture-proof property of the aluminum foil bag? Let's start with the structure:

Common materials: PET/AL/PE? PET/NY/AL/PE? PET/NY/AL/CPP; Thickness: 70 ~ 180 microns;

Aluminum foil packaging features:

(1) strong air barrier performance, anti-oxidation, waterproof, moisture-proof.

(2) strong mechanical properties, high blasting resistance, strong puncture and tear resistance.

(3) high temperature resistance (121℃), low temperature resistance (-50℃), oil resistance, good incense retention performance.

(4) non-toxic and tasteless, in line with food and drug packaging hygiene standards.

(5) good heat sealing performance, flexibility and high barrier performance.

Can be customized according to the requirements of different composite materials and thickness of the product. Storage environment temperature ≤38℃, humidity ≤90%? 5. General product specifications: thickness 0.10mm and 0.14mm, three side sealing, side sealing 10mm, product specifications and sizes can be customized according to customer's needs.

Appearance of aluminum foil packaging bag: opaque, silver-white, anti-gloss, with good barrier, heat sealing, anti-rotation, high temperature resistance, low temperature resistance, oil resistance, fragrance retention; Non-toxic tasteless, soft and other characteristics. It can be seen from the above that the bag with four layers of structure has the best moisture-proof effect. Of course, anti - static bag, shielding bag also has moisture-proof function.
