Abstract
The utility model relates to a super-thick BOPP (biaxially-oriented polypropylene) adhesive tape film, comprising a polypropylene core layer (2). The super-thick BOPP adhesive tape film is characterized in that a glue layer (1) is adhered to the upper surface of the polypropylene core layer (2), and a transparent layer (3) is fixed blow the polypropylene core layer (2). The thickness of the super-thick BOPP adhesive tape film is more than 50 microns, the mechanical properties including tensile strength, a fracture stretching rate and the like of the super-thick BOPP adhesive tape film are superior, and the glossiness, haze and flatness indexes of the super-thick BOPP adhesive tape film reach the standard of an adhesive tape product.
Description
Technical field
The utility model belongs to wrapping material, particularly a kind of superthick BOPP adhesive tape film.
Background technology
The BOPP film production method has periosteum method peace embrane method.Periosteum is owned by France in two-way once step stretching; Flat embrane method is divided into bi-directional synchronization again and stretches and two-way two-step stretch.The periosteum method has that equipment is simple, less investment, occupation of land less, no rim charge loses, simple operation and other advantages.But the shortcoming that, the product thickness tolerance is big with existing production efficiency.The equilibrium of bi-directional synchronization stretching method product lateral performance, rupture of membranes not, set up fully complicated, expensive, rim charge lose many, thickness is restricted.Two-way two-step stretch method equipment maturation, production efficiency height are a kind of methods that most of enterprises select for use.A large amount of on tape at present to adopt thickness be 25 μ, 28 μ, and some is 35 μ, 40 μ, but superthick BOPP adhesive tape film, and thickness does not have a precedent as yet greater than 50 μ adhesive tape films are domestic.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, the high-intensity superthick BOPP adhesive tape film of a kind of thickness greater than 50 μ is provided.
The technical scheme that the utility model technical solution problem adopts is: a kind of superthick BOPP adhesive tape film, comprise polyacrylic sandwich layer, and it is characterized in that on polyacrylic sandwich layer bonding one deck glue-line, fixing layer of transparent layer below polyacrylic sandwich layer.
The beneficial effects of the utility model, this utility model thickness are greater than more than 50 μ, and it is superior that mechanical properties such as rate are stretched in tensile strength and fracture, and glossiness, mist degree and roughness index all reach the adhesive tape product standard.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Figure is the structural front view of superthick BOPP adhesive tape film.
Among the figure: the 1-glue-line; The 2-sandwich layer; The 3-transparent layer.
Embodiment
Embodiment, with reference to accompanying drawing, a kind of superthick BOPP adhesive tape film comprises polyacrylic sandwich layer 2, it is characterized in that on polyacrylic sandwich layer 2 bonding one deck glue-line 1, fixing layer of transparent layer 3 below polyacrylic sandwich layer 2.
Sandwich layer 2 is polypropylene, and its thickness is 50 ~ 60 μ m; The thickness of glue-line 1 is 1 μ m, and the thickness of transparent layer 3 is 1.5 μ m.
Claims (1)
1. a superthick BOPP adhesive tape film comprises polyacrylic sandwich layer (2), it is characterized in that on polyacrylic sandwich layer (2) bonding one deck glue-line (1), fixing layer of transparent layer (3) below polyacrylic sandwich layer (2).
