Because of the above special advantages of aluminum foil composite packaging bags, aluminum foil bags are often used in these areas.
▲First, PC boards, IC integrated circuits, optical drives, hard drives, electronic devices, etc., which need to be packaged in aluminum foil bags to prevent moisture and static electricity.
▲Second, medical care products, etc., which need to be protected from light and oxygen, so aluminum foil bags have a very high advantage in these areas.
▲Third, food, generally used to package meat products, aquatic products, preserved meat, frozen food, seasonings, etc., to preserve the aroma, quality, taste and color.
