Abstract
The invention discloses a kind of Double-side hot sealer, described Double-side hot sealer includes hot sealing layer, sandwich layer, lower hot sealing layer, corona surface from top to bottom, wherein top layer is upper hot sealing layer, upper hot sealing layer is made up of polyethylene copolymer material, the second layer is sandwich layer, sandwich layer is made up of reinforcement and filler, reinforcement is made up of COPP material, filler is made up of HOPP material and binding agent, third layer is lower hot sealing layer, lower hot sealing layer is made up of polyethylene copolymer material, and bottom is corona layer, and corona layer is made up of COPP material.The present invention not only good mechanical performance, the advantages such as heat seal strength is high, also has the high grade of transparency and glossiness, resistance to delineation.
Description
Technical field
The present invention relates to plastic sheeting field, particularly to a kind of Double-side hot sealer.
Background technology
Double-side hot sealer, is 2 faces plastic foils of can be carried out heat sealing, common heat-sealing film mostly by polyethylene or
Polypropylene is made.Need to meet that cold-resistant heat-resisting, peel strength is big, field trash heat sealability is good, glossiness and transparency is good etc. that performance will
Ask.
Existing Double-side hot sealer uses the version of copolymerization of ethylene interlayer mostly, and the surface tension causing film is inadequate,
Antistatic effect is poor.And much there is the problem that thickness fluctuation is big in the Double-side hot sealer on market, the uneven of sandwich layer causes
The defects such as sealing out-of-flatness.
Summary of the invention
The technical problem to be solved is to provide a kind of Double-side hot sealer, and intermediate layer is sandwich layer, and sandwich layer is by strengthening
Muscle and filler composition, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the present invention provides following technical scheme: a kind of Double-side hot sealer, described Double-side hot sealer
Including hot sealing layer, sandwich layer, lower hot sealing layer, corona layer from top to bottom, wherein top layer is upper hot sealing layer, and upper hot sealing layer is gathered by copolymerization
Vinyl material is made, and the second layer is sandwich layer, and sandwich layer is made up of reinforcement and filler, and reinforcement is made up of COPP material,
Filler is made up of HOPP material and binding agent, and third layer is lower hot sealing layer, and lower hot sealing layer is by polyethylene copolymer material
Making, bottom is corona layer, and corona layer is made up of COPP material.
Preferably, described sandwich layer is made up of reinforcement and filler, and the cross section of reinforcement is the sky that the most hexahedro shape is bonded to each other
Heart shape, reinforcement is made up of COPP material, and filler is filled in hollow regular hexahedron, and filler is by HOPP material
Material and binding agent are made.
Preferably, by acrylate adhesive between described upper hot sealing layer, sandwich layer, lower hot sealing layer, each layer of corona layer
Bond.
Use above technical scheme to provide the benefit that: this Double-side hot sealer have employed polyethylene copolymer, COPP,
The mode that the materials such as HOPP combine manufactures, and improves the overall mechanical property of heat-sealing film.Upper and lower hot sealing layer is by copolymerization
Polythene material is made, and has ensured that Double-side hot sealer has good transparency and glossiness, excellent ink and coating attachment
Power.Sandwich layer is made up of reinforcement and filler, and the cross section of reinforcement is the hollow shape that the most hexahedro shape is bonded to each other, and reinforcement is by altogether
Poly-polypropylene material is made, and filler is filled in hollow regular hexahedron, and filler is made up of HOPP material and binding agent,
Improve the heat seal strength of heat-sealing film, and improve heat-sealing film resistance oxygen and the performance of resistance fat migration, improve product quality.Electricity
Dizzy layer is made up of COPP material, by sided corona treatment, makes the surface of stock have higher tack, improves heat
The resistance to delineation performance of sealer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention a kind of Double-side hot sealer；
Fig. 2 is the structural representation of sandwich layer shown in Fig. 1.
Wherein, hot sealing layer, 2 sandwich layers, 3 times hot sealing layers, 4 corona layers, 5 reinforcements, 6 fillers on 1.
Detailed description of the invention
Describe the preferred implementation of the present invention a kind of Double-side hot sealer below in conjunction with the accompanying drawings in detail.
Fig. 1 shows the detailed description of the invention of the present invention a kind of Double-side hot sealer: a kind of Double-side hot sealer, described two-sided heat-sealing
Film includes hot sealing layer 1, sandwich layer 2, lower hot sealing layer 3, corona layer 4 from top to bottom, and wherein top layer is upper hot sealing layer 1, upper hot sealing layer 1
Being made up of polyethylene copolymer material, the second layer is sandwich layer 2, and sandwich layer 2 is made up of reinforcement 5 and filler 6, and reinforcement 5 is gathered by copolymerization
Propylene material is made, and filler 6 is made up of HOPP material and binding agent, and third layer is lower hot sealing layer 3, lower hot sealing layer 3
Being made up of polyethylene copolymer material, bottom is corona layer 4, and corona layer 4 is made up of COPP material.Upper hot sealing layer 1, sandwich layer
2, bonded by acrylate adhesive between lower hot sealing layer 3, each layer of corona layer 4.
Fig. 2 show the structural representation of the sandwich layer of Double-side hot sealer, and sandwich layer 2 is made up of reinforcement 5 and filler 6, strengthens
The cross section of muscle 5 is the hollow shape that the most hexahedro shape is bonded to each other, and reinforcement 5 is made up of COPP material, and filler 6 is filled in
In hollow regular hexahedron, filler 6 is made up of HOPP material and binding agent.
Above is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art,
Without departing from the concept of the premise of the invention, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present invention
Protect scope.
