We know that the name of composite bags is composed of many materials, so we can see that many bags are composite bags, so they are still very common. Some friends may be made of pure aluminum. Why? Let's talk about the specific characteristics of composite bags.

Composite bags are not all made of pure aluminum, but also made of other materials. Aluminum plastic composite bag is a kind of low cost, packaging printing exquisite packaging goods. It has the characteristics of anti-static, anti-ultraviolet, waterproof, oxygen barrier, shading, low temperature resistance, acid and alkali resistance, heat resistance, preservation, oxygen barrier, and strong sealing. According to the bag type, it can be divided into three sides; composite packaging bag; independent vacuum suction cup bag; special composite packaging bag, box bag, special packaging bag, etc.

Aluminum foil composite bags are generally divided into two types. One is polyester PE aluminum foil composite bag. The actual effect of vacuum packaging, cooking and freezing is not very good. There is also a PE aluminum foil polyester composite type, which can be vacuum packaged, cooked and frozen at 121°C. The difference between aluminized bag and aluminum foil bag. The shading ability of the aluminized bag is poor. Pure aluminum bag has a good shading effect. A very simple way to identify the human eye is to put a light effect or sunlight directly in the bag. What you can see through the bag is aluminum plating, what you can't see is aluminum foil.

The material of aluminum foil composite bag is harder and straighter than aluminized packaging bag! And the price is relatively high, pure aluminum bag sweat a lot, I haven't seen it yet! Generally, aluminum foil composite bags are used for meat products, aluminum-plated bags and French fries. It is recommended to use aluminized bags to meet the needs! Light blocking, oxygen blocking tube and moisture blocking properties are excellent, cost-effective.

Special foods of aluminum-plastic composite bags include: vacuum pump aluminum foil bags, yin-nourishing aluminum foil bags, electrostatic shielding bags, grid electrostatic induction bags, shockproof electrostatic induction bags, electrostatic plating process aluminum foil bags and various daily chemical and industrial marks; Used in industrial production and packaging, daily chemical packaging, food packaging materials, pharmaceutical industry, environmental hygiene, electronic devices, aerospace, high-tech, military and other industries; There are the following kinds of aluminum-plastic bags commonly used in daily life: independent food bags, vacuum pump food bags, independent vacuum suction cup beverage bags, special-shaped independent food packaging bags, luggage bags, red wine liquid bags, heat-resistant cooking food packaging bags, aluminum foil tea fresh ground coffee bags, anti-static shielding electronic equipment bags, anti-ultraviolet daily chemical supplies bags, independent hook fitness portable water bags, bone lock briefcases, milk yogurt soybean milk bags.

The above is the "pure aluminum composite bag" we share. I hope what we share can help the friends we need. Even aluminum can be divided into many kinds, so we can make different choices according to the specific requirements of the composite bag, because not all of them are suitable for us.
