Technical field
The present invention relates to a kind of plastic sheeting, especially relate to a kind of shrink sleeve film automatically.
Background technology
Shrink film is widely used in food, medicine, sterilizing dinnerware, stationery sports goods, process gift, leaflet, five metals plastics
The outer package of the various products such as goods, telephone set, electronic apparatus, especially at anomalistic object article or the combination type of commodity
(boundling) packaging aspect, can meet the protection against the tide of commodity dust-proof, touch-proof substitute for another surreptitiously, the function such as transparent display, product can be increased again
Eye appeal, it can also be used to replace all kinds of carton, is not only saved packing cost, and is met packaging trend.
Existing shrink film mainly includes the heat shrink films such as PE, POF, PET.PE heat shrink films is widely used in drinks, easily
Draw the one integral piece assembly package of the products such as tank class, mineral water class, various beverage class, cloth；This product pliability is good, impact resistance, anti-
Lancinating is strong, not cracky, not to be afraid of tide, shrinkage factor big.POF surface gloss height, good toughness, tearing toughness are big, thermal contraction
The features such as uniform and applicable fully automatic high-speed packaging, are the regeneration products of tradition PVC heat shrink films.POF full name is multi-layer co-extruded poly-
Alkene heat shrink films, it is as intermediate layer (LLDPE) using linear low density polyethylene, co-polypropylene (PP) as inside and outside layer,
Extruded by three extruder plasticizings, then process through special process such as die head molding, bubble blown；Production technology is very
Complicated.PET heat shrink films belongs to polyesters, is environment-friendly material, it is easy to recovery and reusing and recycling；But it does not have restoration.
The use of cold events casing tube film in the market is not extensive, and the most existing cold contraction stretching for packaging
Casing tube film, not only chucking power is low, resilience force is weak, penetration-resistant is poor, and production cost is high.
Summary of the invention
It is an object of the invention to provide a kind of shrink sleeve film automatically.
What the present invention solved is that the chucking power that existing shrink film exists is low, resilience force is weak, penetration-resistant is poor, production technology
The defects such as complicated and production cost is high.
The present invention solves technical problem and be the technical scheme is that a kind of shrink sleeve film automatically, and described casing tube film is adopted
Manufacturing by coextrusion film blowing technique, the component of described casing tube film includes that metallocene linear low density polyethylene MLLDPE, line style are low close
Degree polyethylene LLDPE, low density polyethylene, ethylene-octene copolymer POE and functional master batch；Cyclopentadienyl gold in described casing tube film
The percentage by weight belonging to linear low density polyethylene (LLDPE) MLLDPE is 10～15%, the weight hundred of linear low density polyethylene (LLDPE) LLDPE
Proportion by subtraction is 15～20%, and the percentage by weight of low density polyethylene is 35～45%, the weight of ethylene-octene copolymer POE
Amount percentage ratio is 10～40%, and the percentage by weight of functional master batch is 1～15%；The percentage by weight sum of described each component is
100%；Described functional master batch includes anti ultraviolet agent and functional fluoropolymer masterbatch PPA.
Anti ultraviolet agent in described functional master batch is zinc oxide.
In described casing tube film, the percentage by weight of anti ultraviolet agent is 0～1%；The weight hundred of described functional fluoropolymer masterbatch PPA
Proportion by subtraction is 1～15%.
The thickness range of described automatic shrink sleeve film is 50～300 μm.
The invention has the beneficial effects as follows: compared with prior art, the automatic shrink sleeve film that the present invention provides is in use
Just can automatically shrink without heating, enveloped body is packed tightly；Have chucking power height, resilience force is strong, penetration-resistant good, produce work
The advantage such as skill is simple, production cost is low and uvioresistant anti ageing property is good.
