Abstract
The invention discloses a transparent plastic film. The transparent plastic film comprises the following components in percentage by weight: 70 to 80 percent of high density polyethylene, 16 to 25 percent of linear polyethylene and 5 to 7 percent of open agent master batch. The transparent plastic film obtained by proportioning the raw materials has high surface tension, and the surface tension of the film reaches 38 to 44 dynes per centimeters.
Description
Technical field
The present invention relates to a kind of transparent plastic film, particularly a kind ofly improve capillary transparent plastic film.
Background technology
Transparent plastic film is the film of processing with SE, Vilaterm, Vestolen PP 7052, PS and other resins, is used for packing, and as the overlay film layer.
Plastic wrapping and plastic packet product shared share on market is increasing; Particularly composite plastic soft packaging; Fields such as food, medicine, chemical industry have been widely used in; Wherein maximum with the food product pack proportion again, such as drink pack, quickfrozen food packing, cooking food packing, snack food product packing etc., these products all bring great convenience to people's life.
An important index weighing plastics film is a surface tension, and the surface tension of plastics film depends on plastics film surface free energy size, and film surface can depend on the molecular structure of thin-film material itself.Most plastics films such as polyolefin film (LDPE, HDPE, LLDPE, PP) belong to non-polar polymer, and its surface free energy is little, and the wet tension force in surface is lower, is generally about 30 dynes per centimeter.
Theoretically, if object surfaces tension force is lower than 33 dynes per centimeter, common printing ink or tackiness agent just can't adhere firmlys, so must be to its surface treatment.Polyester (PET, PBT, PEN, PETG) is to belong to the polarity polymer, and its surface free energy is higher, and the wet tension force in surface is more than 40 dynes per centimeter.
Generally,, yet need carry out surface treatment, with the wet tension force in its surface of further raising to the BOPET film for the high-speed color printing or for increasing the bonding force between vacuum aluminium coated layer and the BOPET film surface.But so just have more one procedure, be unfavorable for practicing thrift cost.
Summary of the invention
The purpose of this invention is to provide a kind of transparent plastic film, this plastics film surface tension is big.
In order to realize above-mentioned technical purpose, technical scheme of the present invention is:
A kind of transparent plastic film, it comprises following weight percent component:
High density polyethylene(HDPE) 70-80%
Linear polyethylene 16-25%
Opening masterbatch 4-7%.
Preferably, said component percentages is:
High density polyethylene(HDPE) 80%
Linear polyethylene 16%
Opening masterbatch 4%.
The product that proportion of raw materials of the present invention obtains has higher surface tension, and its surface tension reaches the 38-44 dynes per centimeter.

3) raw material after the extruding is carried out curtain coating, cooling, obtain product of the present invention.
Embodiment 3
1) is that 75% high density polyethylene(HDPE), 21% linear polyethylene and 4% opening masterbatch carry out thorough mixing with weight percent, and above-mentioned raw materials is heated to 250 ℃, make raw material become melt;
2) raw material to the melt shape pushes, and the temperature of control extruding is at 230 ℃;
3) raw material after the extruding is carried out curtain coating, cooling, obtain product of the present invention.
Embodiment 4
1) is that 75% high density polyethylene(HDPE), 18% linear polyethylene and 7% opening masterbatch carry out thorough mixing with weight percent, and above-mentioned raw materials is heated to 250 ℃, make raw material become melt;
2) raw material to the melt shape pushes, and the temperature of control extruding is at 230 ℃;
3) raw material after the extruding is carried out curtain coating, cooling, obtain product of the present invention.
The foregoing description does not limit the present invention in any way, and every employing is equal to the technical scheme that replacement or the mode of equivalent transformation obtain and all drops in protection scope of the present invention.
