Abstract
The utility model discloses a low-temperature impact-resistant polyethylene film which is formed by three layers of materials formed by film blowing and co-extrusion; and a middle layer is an elastic layer, and an outer layer and an inner layer are both polyethylene material layers. The elastic layer is formed by the compounding of a polyolefin elastomer and a polyethylene material layer. The polyethylene film can keep better toughness under the low temperature condition, thus improving the impact resistance, meeting the actual packaging needs and having the advantages of both the polyolefin elastomer and the polyethylene.
Description
Technical field
The utility model relates to a kind of low temperature shock resistance polyethylene film, relates in particular to the daily use chemicals class packing polyethylene film that is used under frozen food class and the northern microthermal climate.
Background technology
As everyone knows, polyethylene film is widely used in packaging material such as food, daily use chemicals because of its good heat sealability and processing characteristics.At present, polyethylene film mainly adopts the coextrusion film blowing moulding, and its raw material comprises the metallocene PE of low density polyethylene (LDPE), LLDPE, high density polyethylene (HDPE) and excellent performance etc.Tender property is better under the polyethylene film normal temperature by these feedstock production, can satisfy the shock resistance requirement of packaging film under the general condition, the bale broken phenomenon that packaging bag occurs in handling process can not occur.But be in for a long time in the north under the condition of following low temperature environment of zero degrees celsius and freezing and refrigeration, this polyethylene film is subjected to " freezing " hardening that becomes fragile because of its strand, lose original toughness, bale broken in the packaging bag transportation, often occurs and cause waste, influence the normal use of product.China's utility model patent 200420062971.0 discloses a kind of multifunctional modification polyethylene film on July 20th, 2005, it is by senior middle school density line property polyethylene top layer, and PE modified multipolymer intermediate layer and antipollution sealing line property polyethylene heat-sealing bottom are formed.Though its temperature resistant range and shock resistance improve, but still not ideal enough.
The utility model content
Technical problem to be solved in the utility model just provides that a kind of cost is low, light weight, anti-low temperature, good toughness, the polyethylene film that shock resistance is good.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of low temperature shock resistance polyethylene film, it is characterized in that: described film is made up of the trilaminate material layer that blown film is co-extruded, and wherein the middle level is an elastic layer, and outer and internal layer is the polythene material layer.
Preferably, described elastic layer is the polyolefin elastomer layer.
Preferably, described elastic layer is composited by polyolefin elastomer and polythene material layer.
Preferably, described elastic layer comprises polyolefin elastomer, is coated with polyethylene particle in the described polyolefin elastomer.
Preferably, the ratio of the thickness between described skin, middle level and the internal layer is controlled to be 1: 1: 1.
Preferably, the gross thickness of described film is controlled at 30 μ m～180 μ m.
The utility model is divided into three layers, wherein the middle level is polyolefin elastomer or is polyethylene and polyolefin elastomer blends, polyolefin elastomer (POE) is a kind of anti-impact modifier commonly used, even under cryogenic conditions, also possess excellent shock resistance, the moulding processability excellence is good with the compatibility of vistanex.Under this background, polyolefin elastomer and polyethylene are carried out blending and modifying, by reasonable adding proportion, make polyethylene film under cryogenic conditions, can keep toughness preferably equally, improve its shock resistance, satisfy the virtual package needs.Have the advantage of polyolefin elastomer (POE) and polyethylene (PE) concurrently, therefore the shock resistance buffer capacity of film is better than polyethylene (PE) film, cryogenic conditions performance down is more obvious, the density of polyolefin elastomer (POE) is lower than all polyethylene (PE) simultaneously, can make packaging material weight saving, save cost.
Description of drawings
