Benefits of technology

This new type of plastic bag made from this special material can be used for storing or transportation products that require protection against UV rays during storage periods without losing their quality. It's better than existing materials because it doesn’t lose its effectiveness when exposed to sunlight over time due to less light exposure compared to older methods like vinyl bags.

Problems solved by technology

This patented technical problem addressed by this patents relates to finding an effective way to combine two or more types of plastics together without losing their strength due to poor sealing techniques used during production processes like injection molded containers (IM).

Embodiment 1

[0020] Such as figure 1 As shown, a high-barrier composite film applied to heat insulation boards of the present invention is formed by sequentially heat-sealing the first VMPET film layer 1, VMPET12 film layer 2, the second VMPET film layer 3, and PE heat-sealing layer 4, The first VMPET film layer 1 has a thickness of 10-14 microns, the VMPET12 film layer 2 has a thickness of 12 microns, the second VMPET film layer 3 has a thickness of 10-14 microns, and the PE heat-sealing layer 4 has a thickness of 40-80 microns. A polyurethane adhesive is provided between each adjacent layer.

[0021] In a further embodiment, the PET heat-sealing layer 4 , the first VMPET film layer 1 or the PE heat-sealing layer 4 are provided with laser anti-counterfeiting patterns.

[0022] In a further embodiment, the first VMPET film layer 1 has a thickness of 10 microns, the VMPET12 film layer 2 has a thickness of 12 microns, the second VMPET film layer 3 has a thickness of 10 microns, and the PE heat

Abstract

The invention discloses a high-barrier composite membrane applied to a thermal baffle. The composite membrane is formed by heat sealing of a first VMPET thin film layer, a VMPET12 thin film layer, a second VMPET thin film layer and a PE heat sealing layer in sequence, wherein the first VMPET thin film layer is 10-14 micrometers in thickness, the VMPET12 thin film layer is 12 micrometers in thickness, the second VMPET thin film layer is 10-14 micrometers in thickness, and the PE heat sealing layer is 40-80 micrometers in thickness. The PET heat sealing layer, the first VMPET thin film layer or the PE heat sealing layer is provided with laser anti-counterfeit lines. A packaging film provided by the invention is formed by heat sealing of the first VMPET thin film layer, the VMPET12 thin film layer, the second VMPET thin film layer and the PE heat sealing layer in sequence, thus not only having good thermal insulating performance, but also having the performances of light shading, prevention of ultraviolet irradiation and the like.
