Embodiment 1

[0015] A low-pressure plastic film mainly includes an outer layer, a middle layer and an inner layer, the outer layer and the inner layer are respectively 100% high-density polyethylene; the middle layer includes high-density polyethylene and raw material T12, and the high-density polyethylene The mass percentage of ethylene is 30-50%, and the mass percentage of the raw material T12 is 50-70%. The formula of the original single-layer structure is changed to a three-layer structure, and the original high-density polyethylene is used in the outer layer and the inner layer to maintain the original basic performance, and the middle layer is prepared by mixing high-density polyethylene and raw material T12 , which significantly reduces the production cost of the general formula, and in appearance, the low-pressure plastic film produced by the new formula is brighter and smoother; in terms of transparency, the transparency of the products produced by the new formula and the general f...

[0017] Furthermore, the mass percentage of the high-density polyethylene in the middle layer of the low-pressure plastic film is 40%, and the mass percentage of the raw material T12 is 60%.

[0018] 1) The cost of the existing low-pressure plastic film: taking 100 kg as an example, 50% of high-density polyethylene (HDPE) is 50 kg × 12.6 = 630 yuan + 50% of linear material (7042) is 50 kg × 11.5 = 575 yuan , Total: 1205 yuan / 100 kg.

[0019] 2) The cost of making low-pressure film with new formula: 100 kg as an example, the single layer of plastic film can be divided into inner layer, middle layer and outer layer, the inner and outer layers are fed by one die head, the middle layer is fed by one die head, The feeding speed at the back of the head is the same, so each of the inner and outer layers and the middle layer uses 50 kg of material. The inner and outer layers are made of high-density polyethylene (HDPE) 100%, that is, 50 kg × 12.6 = 630 yuan + the middle layer is made ...

[0021] Furthermore, the thickness of the low-pressure plastic film is 0.015 mm, which is optimal for tensile strength and elongation at break.

[0022] Tensile strength: The low-pressure plastic film produced by the new formula has a thickness of 0.015 mm, its longitudinal tensile strength is ≥30 MPa, and the transverse tensile strength is ≥26 MPa.

[0023] Elongation at break: The low-pressure plastic film produced by the new formula has a thickness of 0.015 mm, and its elongation at break in both longitudinal and transverse directions is ≥100%.

Abstract

The invention discloses low-pressure plastic film, and belongs to the technical field of plastic film production. The low-pressure plastic film mainly comprises an outer layer, an intermediate layer and an inner layer, wherein the outer layer and the inner layer are respectively prepared from 100% high-density polyethylene; the intermediate layer is prepared from high-density polyethylene and a raw material T12; the mass percent of the high-density polyethylene is 30-50%, and the mass percent of the raw material T12 is 50-70%. With modification of the production formula, the production cost is obviously reduced, and the film properties are certainly changed; visually, the low-pressure plastic film produced by the novel formula is brighter and smoother; the transparency of the product produced by the novel formula is rarely different from that of the product produced by the general formula; the tensile strength and the elongation at break of the product are better than that of the product produced by the general formula.

Description

technical field [0001] The invention belongs to the technical field of plastic film production, and in particular relates to a low-pressure plastic film. Background technique [0002] Now, plastic film is widely used in packaging in various industries (for example: televisions, air conditioners, refrigerators, display screens, electronic components, hardware, etc.), and has become an indispensable product in the packaging industry. The existing low-pressure plastic film formula is mainly: high-density polyethylene (HDPE) and linear material (7042) are made in proportion, and the price of polyethylene and linear material is relatively high, and with the development of the economy, The price of raw materials for making plastic film is constantly rising, and the labor cost is also rising, making the production cost higher and higher, and the profit margin of the enterprise is getting smaller and smaller. Therefore, it is necessary to improve the existing product formula, and r...
