A kind of plastic film is conveniently replaceable anti-fold winding device
Technical field
The present invention relates to plastic products field of mechanical technique, specially a kind of plastic film is conveniently replaceable anti-fold winding dress
It sets.
Background technique
The film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, for packing, and
As coating layer.Shared share is increasing on the market for plastics package and plastic packet product, and especially composite plastic is soft
Packaging, has been widely used for the fields such as food, medicine, chemical industry, wherein it is again maximum with food packaging proportion, for example drink
Material packaging, quick-frozen food packaging, cooking food packaging, fast food packaging etc., these products all bring pole to people's life
Big convenience.
Plastic film is most widely used packaging field.Plastic film can be used for food packaging, electric equipment products packaging,
Commodity packaging, garment packaging etc..They have a common ground, exactly will carry out colored printing to plastic film, and make
MULTILAYER COMPOSITE or vacuum aluminum-coated equal technological operations are also carried out for food packaging.It is therefore desirable to which Plastic film surface free energy is wanted
High, wet tension is big, to be conducive to print the good bond of ink, adhesive or aluminium coated and plastic film;In plastic film
Production is batched with during high-speed packaging, then film surface is required to have certain frictional behaviour to prevent film blocking or skidding;In
When for the packaging such as electric appliance, electronic product, then require film that there is certain antistatic performance etc..
The surface tension of plastic film depend on Plastic film surface free energy size, and film surface can depend on it is thin
The molecular structure of membrane material itself.Most plastic films such as polyolefin film (LDPE, HDPE, LLDPE, PP) belongs to apolar polymeric
Object, surface free energy is small, and the wet tension in surface is lower, generally 30 dynes per centimeters or so.Theoretically, if the surface of object
Tension is lower than 33 dynes per centimeters, and common ink or adhesive just can not adhesion-tights, it is therefore necessary to be surface-treated to it.It is poly-
Esters (PET, PBT, PEN, PETG) are to belong to polarity macromolecule, and surface free energy is higher, and the wet tension in surface is in 40 dynes/li
Meter or more.But high-speed color is printed or to increase the binding force between vacuum aluminium coated layer and BOPET film surface, also
It needs to be surface-treated BOPET film, to further increase the wet tension in its surface.
