Aluminum foil three-dimensional bags (moisture-proof bags, aluminum plastic composite bags, vacuum bags, large three-dimensional moisture-proof bags) can be equipped with vacuum valve ports, which have good water resistance, gas resistance, and moisture resistance functions. The material feels comfortable, smooth, strong, and flexible. Has good protective properties: oxygen resistance, moisture resistance, puncture resistance, high strength, high toughness, can be breathable in one or both directions, resistant to strong ultraviolet rays, chemical resistance, and resistance to oil and acid and alkali substances.

Explanation: Using different process formulas to achieve different standards for water vapor and oxygen transmittance.

Bag selection: three-dimensional bags or irregular bags.

Bag printing: Printing text, patterns, and trademarks in different specifications, thicknesses, and styles.
