Embodiment Construction

[0023] 1. For BOPP printing film

[0024] The BOPP printed film is a product purchased from Anhui Guofeng Plastic Industry. The BOPP printed film not only maintains excellent optical properties, smoothness and heat shrinkability, but also has good stiffness, high elastic modulus, uniform thickness, and a smooth film surface. It also has a certain degree of wear resistance and can be applied to high-speed automatic packaging processes.

[0025] 2. For aluminum oxide-coated PET film

[0026] The preparation of aluminum oxide coated PET film of the present invention:

[0027] The first group: put the reel PET film base material in the vacuum chamber and then carry out the vacuuming operation. When the vacuum degree in the vacuum chamber reaches 4×10 -4 When the temperature is above mba, the evaporation boat is heated up to 1500°C, and then the aluminum wire with a purity of 99.9% is continuously sent to the evaporation boat, so that the aluminum wire is continuously melted and ...

Abstract

The invention relates to a transparent high-barrier film applicable to high-speed automatic packaging and a production method thereof. The material structure of the transparent high-barrier film comprises a BOPP printing film layer, an aluminum oxide plated PET film layer and a PE film layer, wherein the aluminum oxide coating of the aluminum oxide plated PET film layer is compounded with a printed surface of the BOPP printing film layer; the thickness of the aluminum oxide coating is 0.15 to 0.25 micrometers; the thickness of the BOPP printing film layer is 18 to 20 micrometers; the thicknessof the aluminum oxide plated PET film layer is 12 to 14 micrometers; the thickness of the PE film layer is 30 to 35 micrometers. The transparent high-barrier film not only has barrier property on oxygen and water vapor, but also has excellent odor barrier property, has fragrance keeping function, and further has excellent transparency and heat sealing strength.

Description

Technical field: [0001] The invention belongs to the field of film materials, and in particular relates to a transparent high-barrier film suitable for high-speed automatic packaging and a production method thereof. Background technique: [0002] With the advancement of chemical technology, the functional development trend of plastic packaging films is becoming more and more obvious. Among them, high-barrier plastic packaging films are one of the fastest-growing functional films. High-barrier film refers to a packaging film that protects the contents of the package from the infiltration of pollutants and small molecules such as oxygen, water vapor, liquids, and odors, and also prevents the contents of the package from seeping out. The high barrier property of high barrier film means that under the standard state of 23°C and 65% relative humidity, the oxygen transmission rate is less than 5ml / m 2 ·Less than one day, water vapor transmission rate <2g / m 2 d.
