Abstract
The utility model relates to a heated adhesive synthetic papers, consisting of a both-way stretched three layers structure of a core layer, a upper layer and a lower layer through a co-extruding. Therein the core layer is a bubble layer, consisting of a homopolymerization polypropylene rosin, a calcium carbonate compound, and a plurality of auxiliary agents of a antistatic agent and titanium dioxide, etc, the upper and lower layer are heat sealing layers, consisting of a ethane- propylene- butylene terpolymer, a propylene- butylene random copolymer and a polymer of the combination of two parts above. Adding an proper amount of antisticking agent, the lower layer is also a unheat sealing layer, namely the homopolymerization polypropylene rosin added antisticking agent with a weight percentage 0-4.0%, and the wetting tension of the paper can reach 38-46mN/m after a double-face or single-face corona treatment. The utility model has the advantages of high synthetic papers heat sealing intensity, firm surface printing, good resistance to elements, good tearing toughness and no environmental pollution, the used synthetic papers can be produced to other plastic products after recovering totally to decrease the use-cost of the users.
Description
Technical field
The utility model belongs to a kind of wrapping paper, particularly relates to a kind of heat-sealing type synthetic paper that is used for packings such as seed, food and electronic device.
Background technology
Being widely used in packings such as seed, food and electronic device at present adopts paper compound mostly, promptly with paper wood as base layer structure, is raw material on its surface with polyethylene (PE), after adopting combination process or drenching membrane process processing, obtain heat cover and make above-mentioned packaging bag, though it is this paper and plastics compound bag has lucifuge, function such as heat sealable, bigger in papermaking, consumption compound, that drench water, electricity, vapour in the film production process, the processing cost height, and cause environmental pollution aborning; In addition paper plastic combined package bag be subject to factor affecting such as complex condition, storage environment and layering appears, problem such as break, so not only influence result of use, but also can bring corresponding economic loss to the user; Above-mentioned compound paper bag can't be done effective recycling with recovery systems such as natural paper or plastic cement after use, this waste and feature of environmental protection to resource all has adverse influence.
Summary of the invention
The utility model provides for solving the technical problem that exists in the known technology that but a kind of one-shot forming, heat seal strength height, weather resisteant are good, light weight, opacity height, attractive in appearance and suitable industrial continuous production heat-sealing type synthetic paper.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
The heat-sealing type synthetic paper, it comprises that through the sandwich layer of coextrusion biaxial tension, the upper and lower three-decker, its center core layer is foaming layer, and the upper and lower are hot sealing layer, and described lower floor also can be non-hot sealing layer.
The utility model can also adopt following technical measures:
The gross thickness of described synthetic paper is designed to the 50-150 micron, and its density is the 0.55-0.85 gram per centimeter
3
Advantage and the good effect that the utlity model has are: because the upper and lower of the present utility model all by the heat-sealing one-shot forming, need not compound in manufacturing process again or drench technology such as film, simplified processing technology, the reduction manufacturing cost; Make the synthetic paper that processes have heat seal strength height, heat-sealing temperature wide ranges, surface printing firmly, advantage such as light weight: and be not subjected to the influence of factors such as complex condition and storage environment, its weather resisteant is good, tearing toughness good; All production processes can not produce any harmful substance, and non-environmental-pollution, the synthetic paper after the use can all reclaim makes other plastic products, but energy savings not only, but also reduced user's use cost.

Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Among the figure: 1 upper strata, 2 sandwich layers, 3 lower floors.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Embodiment 1
See also Fig. 1, the heat-sealing type synthetic paper, it comprises the three-decker of sandwich layer 2, upper strata 1 and lower floor 3 through the coextrusion biaxial tension, its center core layer 2 is foaming layer, upper strata 1 and lower floor 3 are hot sealing layer, and its gross thickness is designed to the 50-150 micron, and its density is the 0.55-0.85 gram per centimeter
3Described sandwich layer 2 also is added with the compound of calcium carbonate that percentage by weight is 2.0-16.0%, the antistatic additive of 0.5-4.0% and the auxiliary agents such as titanium dioxide compound of 0-10.0% for the sandwich layer that the HOPP resin constitutes in the HOPP resin.Described upper strata 1 and lower floor 3 constitute, can also constitute for the polymer of ethylene-propylene-butene-1 terpolymers and ethylene-propylene random copolymer blend for ethylene-propylene-butene-1 terpolymers constitutes, also can be ethylene-propylene random copolymer, also are added with the anti-adhesive agent that percentage by weight is 0-4.0% in above-mentioned copolymer and polymer.According to above-mentioned batching, the material that the material of sandwich layer 2 goes out machine, upper strata 1 and lower floor 3 through a master respectively through two auxilliary extruder fusions, plastify, be expressed into a flat T type mouth mould coextrusion, the compound film sheet that flows out from flat T type mouth mould is through cooling, again through longitudinal stretching, cross directional stretch, then after side cut, thickness measuring, sided corona treatment rolling on spool.Wherein sided corona treatment can two-sided sided corona treatment promptly be handled upper strata 1 and lower floor 3 simultaneously; Perhaps the single face sided corona treatment is promptly handled lower floor 3, and its wetting tension of synthetic paper after treatment reaches 38-46mN/m.
