Abstract
The invention discloses a red plastic film. The red plastic film comprises the following components in percentage by weight: 60 to 70 percent of high density polyethylene, 16 to 25 percent of linear polyethylene, 10 to 12 percent of red master batch and 5 to 7 percent of open agent master batch. The red plastic film obtained by proportioning the raw materials has high surface tension, and the surface tension of the film reaches 36 to 43 dynes per centimeters.
Description
Technical field
The present invention relates to a kind of red plastic film, particularly a kind ofly improve capillary red plastic film.
Background technology
The red 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.
Recently, colored plastics film mass production, the adding of Masterbatch has changed the molecular structure of thin-film material itself, and so just the surface tension to plastics film produces certain influence.
Summary of the invention
The purpose of this invention is to provide a kind of red plastic film, this plastics film is eliminated and is colored in raw material to capillary influence through to proportion of raw materials.
In order to realize above-mentioned technical purpose, technical scheme of the present invention is:
A kind of red plastic film, it comprises following weight percent component:
High density polyethylene(HDPE) 60-70%
Linear polyethylene 16-25%
Red masterbatch 10-12%
Opening masterbatch 3-5%.
Preferably, said component percentages is:
High density polyethylene(HDPE) 60%
Linear polyethylene 25%
Red masterbatch 10%
Opening masterbatch 5%.
The product that proportion of raw materials of the present invention obtains has higher surface tension, and its surface tension reaches the 36-43 dynes per centimeter.
