Abstract
The utility model provides an improved compound film which comprises a surface layer, a sandwich layer and a bottom layer in sequence from the top down, wherein the surface layer is a binary co-polypropylene layer; the sandwich layer is a PP (Propene Polymer) drawn wire layer; and the bottom layer is a ternary co-polypropylene layer. In the improved compound film adopting the technical scheme, as the bottom layer is a ternary co-polypropylene layer and the heat-seal melt temperature of ternary co-polypropylene is 118 DEG C and lower than that of binary co-polypropylene, compared with the prior art, the improved compound film can reduce the heat-seal temperature of a bag-making machine while being used for preparing heat-sealed bags, thereby reducing the ambient temperature of the bag-making machine, improving the work environment of bag makers and increasing the production efficiency of the bag-making machine.
Description
Technical field
The utility model relates to a kind of laminated film, particularly a kind of wrapping laminated film.
Background technology
The heat-sealing bag is last procedure in the plastic compound flexible packaging production process.It is to utilize extraneous heating to make the heat-sealable material of laminated film heat-seal land become the viscosity flow state, and by means of the pressure of heat-sealing cutter, two-layer heat-sealable material fuses together each other about making, and the cooling back keeps certain intensity, has good sealing property.
Existing wrapping laminated film, it is generally layer structure, from top to bottom is followed successively by superficial layer, sandwich layer and bottom, and wherein superficial layer and bottom are binary atactic copolymerized polypropene layer, and sandwich layer is the PP wire drawing bed of material.But the laminated film of this structure; Its superficial layer and bottom are binary atactic copolymerized polypropene layer; And the heat-sealing melt temperature of binary atactic copolymerized polypropene is 135 ℃, and heat-sealing temperature often will be higher than the melt temperature of heat-sealable material in the compound bag process of heat-sealing, and the operating temperature that when sealing operation, adopted of Bag Making Machine is higher like this; Make the surrounding enviroment temperature of Bag Making Machine; Thereby make bag workman's working environment relatively poor, and can influence the production efficiency of Bag Making Machine, reduced the production efficiency of Bag Making Machine.
The utility model content
The purpose of the utility model is to provide a kind of modified laminated film; It can reduce the heat-sealing temperature of Bag Making Machine when being used to prepare the heat-sealing bag; Thereby reduced the surrounding enviroment temperature of Bag Making Machine, improved bag workman's working environment, and improved the production efficiency of Bag Making Machine.
The technical scheme that the utility model adopted is such: a kind of modified laminated film, from top to bottom comprise superficial layer, sandwich layer and bottom successively, and wherein superficial layer is the binary copolymerization polypropylene layer, sandwich layer is the PP wire drawing bed of material; Above-mentioned bottom is the ternary polymerized polypropylene layer.
Above-mentioned ternary polymerized polypropylene layer is the ternary polymerized polypropylene layer of FL7632L for its trade mark.
After adopting technique scheme, a kind of modified laminated film of the utility model is because bottom is the ternary polymerized polypropylene layer; And the heat-sealing melt temperature of ternary polymerized polypropylene is 118 ℃, and is lower than the polyacrylic heat-sealing melt temperature of binary copolymerization, compared with prior art; The laminated film of the utility model; When being used for preparation heat-sealing bag, can reducing the heat-sealing temperature of Bag Making Machine, thereby reduce the surrounding enviroment temperature of Bag Making Machine; Improve bag workman's working environment, and improved the production efficiency of Bag Making Machine.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure:
The specific embodiment
A kind of modified laminated film of the utility model; From top to bottom comprise superficial layer 1, sandwich layer 2 and bottom 3 successively, wherein superficial layer is the binary copolymerization polypropylene layer, and it is the binary copolymerization polypropylene of Y131 that this binary copolymerization polypropylene adopts its trade mark; Sandwich layer 2 is the PP wire drawing bed of material; The PP wire drawing material of this PP wire drawing bed of material is PP wire drawing material T30S, and bottom 3 is the ternary polymerized polypropylene layer, and it is the ternary polymerized polypropylene of FL7632L that this ternary polymerized polypropylene adopts its trade mark.
A kind of modified laminated film of the utility model, because bottom 3 is the ternary polymerized polypropylene layer, and the heat-sealing melt temperature of ternary polymerized polypropylene is 118 ℃; Lower than the polyacrylic heat-sealing melt temperature of binary copolymerization, compared with prior art, the laminated film of the utility model; When being used to seal bag, can reduce the heat-sealing temperature of Bag Making Machine, thereby reduce the surrounding enviroment temperature of Bag Making Machine; Improve bag workman's working environment, and improved the production efficiency of Bag Making Machine.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
Claims (2)
1. a modified laminated film from top to bottom comprises superficial layer, sandwich layer and bottom successively, and wherein superficial layer is the binary copolymerization polypropylene layer, and sandwich layer is the PP wire drawing bed of material; It is characterized in that: above-mentioned bottom is the ternary polymerized polypropylene layer.
2. a kind of modified laminated film according to claim 1 is characterized in that: above-mentioned ternary polymerized polypropylene layer is the ternary polymerized polypropylene layer of FL7632L for its trade mark.
