As another embodiment of this case, wherein, in VC glue-line, 4 also include modifying agent, and this modifying agent includes:
The effect of modifying agent is to slow down the problem that VC glue elapses in time and the heat seal strength that produces drastically declines, to improve The stability of VC glue heat seal strength and persistency so that even with the mode of fixed point coating, also will not subtracting because of spreading area Little and affect the heat seal strength of VC glue.Above-mentioned formula is as an entirety, and its respective ratio should be severely limited.But research Finding, the molecular weight of the polymer in above-mentioned formula is the least on the impact of its performance, it is therefore not necessary to polymer each in formula Molecular weight defines.Carboxylic styrene butadiene latex and Polyethylene Glycol are mainly used in improving VC glue adhesion strength at high temperature, and Antioxygen property to air；Isopropyl acid N-butyl is mainly used in regulating VC glue and is heat-sealed to the speed of solidification from high temperature, meanwhile, different Another effect of n-butyl propionate is to reduce shrinkage stress when VC is gelled solid, to improve the stability of heat-sealing；Ethylene-methyl The effect of ethyl acrylate copolymer is to reduce VC glue deformation amplitude at high temperature, increases VC glue viscosity at high temperature simultaneously Coefficient, thus reduce its mobility, so that VC glue still can keep higher heat seal strength under less spreading area.
Except resin base material, modifying agent in VC glue, may preferably further comprise routine dispersant or surfactant, but this A little dispersants or surfactant need to be only that adhesive field is conventional, and therefore this case no longer limits at this.
In the above-described embodiments, resin base material and modifying agent contain a preferred adding proportion, the most in parts by weight, tree Aliphatic radical material: modifying agent=100: 10-20.
In the above-described embodiments, in ethylene-ethyl methacrylate copolymer, ethylene contents is preferably 31-33wt%, remaining Amount is ethyl methacrylate.In order to ensure that the effect of ethylene-ethyl methacrylate copolymer is to reduce deformation amplitude and increasing Add viscosity coefficient, need ethylene contents therein is defined.
