Technical Field
The utility model belongs to the technical field of food package and specifically relates to a heat-seal film that easy heat-seal was easily uncovered is related to.
Background
Heat-seal bag system generally uses in food package field, and the heat-seal film is one of the materials that uses in the heat-seal bag system, and its heat-seal effect of traditional heat-seal film is relatively poor, often appears the phenomenon that produces the small opening after the heat-seal to influence the leakproofness of the food packaging area that the heat-seal film was made, traditional heat-seal film system wrapping bag also is comparatively hard when needs are uncovered simultaneously.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve the above-mentioned problem of proposing, provide a heat-seal film that easy heat seal was easily uncovered for this reason, including the basic unit, be provided with the hot melt adhesive layer on the lower terminal surface of basic unit, one side that the basic unit was kept away from to the hot melt adhesive layer is provided with down the heat-seal layer, be provided with the tin coating on the up end of basic unit, one side that the basic unit was kept away from on the tin coating is provided with the matte layer, be provided with a plurality of interval hole in the matte layer, be provided with a plurality of pearl-lustre granule in the interval hole, one side that the matte layer was kept away from to the matte layer is provided with the heat-seal layer, it is provided with the.
Preferably, the matte layer is silica particles, and the silica particles are uniformly paved on the tin-plated layer through a sand blasting process.
Preferably, the base layer is a PE layer.
Preferably, the upper heat-sealing layer and the lower heat-sealing layer are made of polyethylene.
Preferably, the corona layer is made of polypropylene.
The utility model has the advantages that: the utility model has the advantages of reasonable design, can effectively improve the heat-seal effect of heat-seal membrane to the sealed effectual of wrapping bag after the heat-seal, also be convenient for simultaneously open the wrapping bag when opening the wrapping bag.
Drawings
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
fig. 1 is a schematic sectional view of the present invention;
fig. 2 is a schematic sectional structure diagram of the present invention;
in the figure: 1. a base layer; 2. a hot melt adhesive layer; 3. a lower heat seal layer; 4. electroplating layer; 5. a matte layer; 6. an upper heat sealing layer; 7. a spacer hole; 8. pearlescent particles; 9. and (4) a corona layer.
Detailed Description
All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.
Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
The heat-sealing film easy to heat and seal and easy to uncover as shown in fig. 1 comprises a base layer 1, a hot-melt adhesive layer 2 is arranged on the lower end face of the base layer 1, a lower heat-sealing layer 3 is arranged on one side, away from the base layer 1, of the hot-melt adhesive layer 2, a tin-plated layer 4 is arranged on the upper end face of the base layer 1, a matte layer 5 is arranged on one side, away from the base layer 1, of the tin-plated layer 4, a plurality of interval holes 7 are formed in the matte layer 5, a plurality of pearl particles 8 are arranged in the interval holes 7, an upper heat-sealing layer 6 is arranged on one side, away from the tin-plated layer 4, of the matte layer 5, and a corona layer 9 is arranged.
The matte layer 5 is silica particles, and the silica particles are uniformly paved on the tin-plated layer 4 by the matte layer 5 through a sand blasting process.
The base layer 1 is a PE layer.
The upper heat-sealing layer 6 and the lower heat-sealing layer 3 are made of polyethylene.
The corona layer 9 is made of polypropylene.
As shown in fig. 2, the pearlescent particles 8 are arranged as diamond-shaped pearlescent sheets sandwiched in the matte layer 5.
In the use process, the hot melt adhesive layer 2 is arranged to assist the lower heat-sealing layer 3 to carry out heat-sealing, the tin-plated layer 4 is arranged to increase the strength of the base layer 1 and facilitate the uncovering of the heat-sealing film, the matte layer 5 is arranged to improve the brightness of the tin-plated layer 4, so that the heat-sealing film is brighter and more attractive, and the pearl particles 8 are arranged to further improve the brightness of the tin-plated layer 4.
The utility model has the advantages that: the utility model has the advantages of reasonable design, can effectively improve the heat-seal effect of heat-seal membrane to the sealed effectual of wrapping bag after the heat-seal, also be convenient for simultaneously open the wrapping bag when opening the wrapping bag.
The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
