Description
Technical field
The utility model is related to a kind of super cool sliding two-sided heat-sealing type bidirectional stretching polypropylene films, belong to biaxial stretching polypropylene
Alkene thin film processing techniques field.
Background technology
Because polypropylene film (BOPP) has good mechanical property and excellent glossiness, relatively low density is (i.e. identical
Mass unit area is big), it was rapidly developed, was especially widely applied in packaging field in recent years.It was subject to lower visitor in recent years
Work cost limits, and automatic packaging machine is widely applied, and especially in American-European and Japan, packaging speed is continuously improved, and this requires products
There is Self-enclosing, with the raising of machine speed, coefficient of friction is required less and less.With the raising of packaging speed,
Product transmission process frictional heating, traditional product because temperature rise it is tacky due to coefficient of friction increase.
Utility model content
To make up the deficiencies in the prior art, the utility model is provided for the exploitation of the fields such as domestic and international paper handkerchief, tealeaves, playing card
There is the Polypropylene film of relatively low thermal friction coefficient and heat seal strength.
The technical solution of the utility model is as follows：Super cool sliding two-sided heat-sealing type bidirectional stretching polypropylene film, from top to bottom
Upper epidermis, sandwich layer, layer are followed successively by, the upper epidermis is formulated by copolymer polypropylene, slipping agent and antitack agent；It is described
Sandwich layer be formulated by homopolypropylene, antistatic agent, slipping agent；The layer by copolymer polypropylene, elastomer and
Antitack agent is formulated.The chemical materials such as copolymer polypropylene, elastomer, the antitack agent are this field convenient source.Institute
The upper table layer thickness stated is 1 μm, following table layer thickness is 1.5 μm, and the core layer thickness is 10.0-25.0 μm.The copolymerization
Polypropylene is ternary polymerized polypropylene；Slipping agent is not migrate silicone slipping agent in the upper epidermis.The layer is
Corona processing layer.
Further, the antitack agent is spherical shape PMMA classes (polymethacrylates) antitack agent.
The beneficial effects of the utility model are as follows：Super cool sliding two-sided heat-sealing Biaxially oriented polypropylene provided by the utility model
Film has lower coefficient of friction, and can also keep low-friction coefficient in hot environment.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Wherein：1st, upper epidermis, 2, sandwich layer, 3, layer.
Specific embodiment
As shown in Figure 1, super cool sliding two-sided heat-sealing type bidirectional stretching polypropylene film, is followed successively by upper epidermis 1, core from top to bottom
Layer 2, layer 3, the upper epidermis 1 are formulated by copolymer polypropylene, slipping agent and antitack agent；The sandwich layer 2 is by equal
Poly- polypropylene, antistatic agent, slipping agent are formulated；The layer 3 is prepared by copolymer polypropylene, elastomer and antitack agent
It forms.1 thickness of upper epidermis is 1 μm, 3 thickness of layer is 1.5 μm.2 thickness of sandwich layer is 25.0 μm.Described
Copolymer polypropylene is ternary polymerized polypropylene；Slipping agent is not migrate silicone slipping agent in the upper epidermis 1.Described is anti-sticking
Agent is spherical shape PMMA class antitack agents.The layer 3 is corona processing layer.
Above-described embodiment is only used for illustrating the inventive concept of the utility model rather than to the utility model rights protection
Restriction, all non-essential modifications to the present invention made by this concept should all fall into the protection model of the utility model
It encloses.
