Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0014] As shown in the figure, an embodiment of the cold film for anti-ultraviolet trayless packaging of the present invention is provided, which is sequentially co-extruded from the first layer 1, the second layer 2, and the third layer 3 materials. The first layer 1 material accounts for 20%-30%, the second layer 2 material accounts for 40%-60%, and the third layer 3 material accounts for 20%-30%;

[0015] In terms of mass fraction, the first layer of materials includes: metallocene raw materials accounting for 90%-95%, functional masterbatch accounting for 5%-10%;

[0016] In terms of mass fraction, the second layer of materials includes: ethylene-vinyl acetate copolymer raw materials accounted for 5%-95%, high-pressure raw materials accounted for 5%-15%, functional masterbatch accounted for 5%-10%;

[0017] In terms of mass fraction, the third layer of materi...

Abstract

The invention discloses an anti-ultraviolet cold film for pallet-free packaging. The anti-ultraviolet cold film is prepared from 20%-30% by mass of a first-layer material, 40%-60% by mass of a second-layer material and 20%-30% by mass of a third-layer material by co-extruding in sequence, wherein the first-layer material comprises 90%-95% of raw metallocene and 5%-10% of functional masterbatch; the second-layer material comprises 5%-95% of raw EVA (ethylene vinyl acetate), 5%-15% of a raw high-pressure material and 5%-10% of the functional masterbatch; the third-layer material comprises 90%-95% of raw metallocene and 5%-10% of the functional masterbatch. The anti-ultraviolet cold film for pallet-free packaging is applicable to pallet-free packaging and is high in strength, good in tensile property, high in wrapping performance and not prone to deformation, a product can be prevented from bulging or being damaged during pallet-free packaging, and an anti-ultraviolet function can be realized by means of an added anti-ultraviolet agent.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a cold film for anti-ultraviolet trayless packaging. technical background [0002] The cold film for packaging is used to wrap the goods, making the packaged products more stable and tidy, and at the same time play the role of waterproof and dustproof. The cold film for non-tray packaging needs to ensure that the product does not protrude when it is packaged without a tray. There are high requirements for the tensile performance and deformation resistance of the cold film for packaging. The existing cold film for packaging is not strong enough, and the resistance The tensile performance is not good enough, it is easy to deform, and it has no anti-ultraviolet effect, so it needs to be improved urgently. Contents of the invention [0003] The invention provides a cold film for anti-ultraviolet trayless packaging. [0004] The purpose of the invention is to solve the...
