The invention relates the paint film material used for color printing, comprising polypropylene base-material, and elastoviscous polymer and addition agent. The stickiness compound comprises low density polyethylene, linear low density polyethylene, vinyl acetate, vinyl copolymer and olefin copolymer. The addition agent comprises dispersing agent and anti-oxidizing agent. The material comprises 65.98-89.8wt% polypropylene, 7-14wt% low density polyethylene, 1-4wt% linear low density polyethylene, 1-8wt% olefin copolymer, 0.01-0.1wt% dispersing agent and 0.01-0.1wt% anti-oxidizing agent. The olefin copolymer comprises propone, hexane and vinyl copolymer, the dispersing agent is polyethylene wax and polypropylene wax, the anti-oxidizing agent is heat-durability phenolic compound or phosphite ester compound. The above materials are mixed, granulated, dewatered, screened and checked, and the product is made.
Description
Technical field
The present invention relates to a kind of special-purpose film-coating material for polypropylene color printing, particularly a kind of food color printing packing that is used for is answered the special-purpose film-coating material for polypropylene color printing that film is used.
Background technology
Existing domestic and international food pack, usually all has prismy color printing packing, because color printing pigment generally all contains various chemical ingredientss, as some also can cause certain murder by poisoning to enter human body, therefore to be intercepted with nontoxic, harmless polypropylene film usually.Because the preparation of such polypropylene film material has certain difficulty, thereby domestic food enterprise adopts the coating materials from external import mostly, and that these products often exist is on the high side, the deficiency of performance less stable sometimes.
Summary of the invention
The objective of the invention is to provide the special-purpose film-coating material for polypropylene color printing of a kind of low price, excellent property, reach existing higher product quality, the effect that price is lower again.
Task of the present invention is achieved through the following technical solutions:
A kind of special-purpose film-coating material for polypropylene color printing, comprise polypropylene base-material, sticky polymers, additive, it is characterized in that: described sticky polymers comprises new LDPE (film grade), linear low density polyethylene, vinyl acetate between to for plastic and ethylene copolymer and polyolefine terpolymer; Described additive comprises dispersion agent, fire-resistant oxidation resistant agent; The weight percent that this special-purpose film-coating material for polypropylene color printing is formed is:
Polypropylene 65.98～89.8%;
New LDPE (film grade) 7～14%;
Linear low density of polyethylene 1～4%;
Vinyl acetate between to for plastic and ethylene copolymer 1～4%;
Polyolefine terpolymer 1～8%;
Dispersion agent 0.01～0.1%;
Antioxidant 0.01～0.1%
Described polyolefine terpolymer is made up of propylene, hexene, ethylene copolymer.Dispersion agent is made up of polyethylene wax and/or Poly Propylene Wax.And antioxidant can be the thermotolerance phenolic compound, also can be phosphite ester compound.
With said components, be prepared from special-purpose film-coating material for polypropylene color printing through as shown in Figure 1 mixing, granulation, dehydration, screening, quality inspection operation according to the material of aforementioned proportioning.
The present invention compared with prior art has following characteristics and technical progress:
Adopt sticky polymers of the present invention, dispersion agent and antioxidant to realize mixing in mixing, granulating working procedure, it is dispersed in the polypropylene base-material, and reach certain flow rate, thereby thereby improved the stripping strength that the cementability of filming has improved polypropylene screen, also improved stripping strength with colored ink, higher flow rate also makes it can be fit to height and replies immediately film production simultaneously, and its speed can reach 150 meters/minute～245 meters/minute.And product processing characteristics of the present invention is stable, and is better with the dispersiveness of colour batch, reduced its cost when scale production.In addition, it also is improved largely in performance index such as deflection, transparency, smells, and performance can compare favourably with the like product of external production.
The alternative imported product of the present invention is widely used in color printing packing internal layers such as BOPP, OPP, the CPP occasion of films again, can be suitable for preparing food resistance light, oxygen barrier fresh-keeping packaging bag especially, as instant noodles, bread packing bag etc.
