Embodiment 1

[0028] The high-temperature-resistant film of this embodiment includes three parts: an outer layer, a middle layer and an inner layer. The weight of the outer layer accounts for 10% of the total weight of the film, the weight of the middle layer accounts for 60% of the total weight of the film, and the weight of the inner layer accounts for 30% of the total weight of the film. , where, by weight percentage,

[0029] The raw materials for the preparation of the outer and inner layers are PP M800E;

[0030] The raw material for the middle layer is composed of 80% MDPE 5400 and 20% LDPE TN00.

[0031] The preparation method of the high temperature resistant film of the present embodiment is as follows:

[0032] 1) mixing materials, mixing the preparation raw materials of the middle layer of the formula amount to prepare the middle layer raw material mixture of the high temperature resistant film;

[0033] 2) batching, the middle layer raw material mixture of the high temperature ...

Embodiment 2

[0036] The high-temperature-resistant film of this embodiment includes three parts: an outer layer, a middle layer, and an inner layer. The weight of the outer layer accounts for 30% of the total weight of the film, the weight of the middle layer accounts for 50% of the total weight of the film, and the weight of the inner layer accounts for 20% of the total weight of the film. , where, by weight percentage,

[0037] The raw materials for the preparation of the outer and inner layers are PP M800E;

[0038] The raw material for the middle layer is composed of 60% MDPE 5400 and 40% LDPE TN00.

[0039] The preparation method of the high temperature resistant film of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Embodiment 3

[0041] The high-temperature-resistant film of this embodiment includes three parts: an outer layer, a middle layer and an inner layer. The weight of the outer layer accounts for 30% of the total weight of the film, the weight of the middle layer accounts for 60% of the total weight of the film, and the weight of the inner layer accounts for 10% of the total weight of the film. , where, by weight percentage,

[0042] The raw materials for the preparation of the outer and inner layers are PP M800E;

[0043] The raw material for the middle layer is composed of 70% MDPE 5400 and 30% LDPE TN00.

[0044] The preparation method of the high temperature resistant film of this embodiment is the same as that of Embodiment 1, and will not be repeated here.

Abstract

The invention provides a high-temperature-resistant film and a preparation method thereof, and belongs to the technical field of films. The high-temperature-resistant film comprises an outer layer, a middle layer and an inner layer, wherein the outer layer is 10%-30% of total weight of the film, the middle layer is 50%-70% of total weight of the film, and the inner layer is 10%-30% of total weight of the film; the outer layer and the inner layer are prepared from PP M800E; the middle layer is prepared from the following components in percentage by weight: 60%-80% of MDPE 5400 and 20%-40% of LDPE TN00. The high-temperature-resistant film provided by the invention is simple in structure and has good impact resistance and tear resistance, the performance of the high-temperature-resistant film is not changed in a high-temperature environment, substances harmful to a human body are not released, and the thermal distortion temperature can reach 150 DEG C or above.

Description

technical field [0001] The invention belongs to the technical field of thin films, and relates to a high temperature resistant thin film and a preparation method thereof. Background technique [0002] With the change of people's living habits, more and more fast-moving foods appear. These fast-moving foods will use food packaging films during storage and transportation. Food packaging films are used to wrap food surfaces, mainly for isolation A polymer material that decomposes the entry of microbial bacteria and foreign pollutants, and prevents and prolongs food spoilage. In addition to meeting the mechanical properties, printing properties, display properties and other properties that packaging materials must have for food packaging films, countries all over the world have high requirements for the hygienic properties of packaging materials for food items. Normal color, no peculiar smell, high temperature resistance, antibacterial, etc. At present, many fast-moving consum...
