Description
Technical field
The invention belongs to thin film technique fields, and in particular to a kind of packing film and preparation method of superpower wear-resistant.
Background technique
Existing packing film, prepares that material is relatively simple, causes the wear-resisting property of packing film poor.Especially cigarette
Packing film still has very big deficiency on wear-resisting property.Requirement with cigarette industry to cigarette film product is more next
Higher, visually other than low haze to be had, high gloss, superpower wear-resistant performance becomes and compels to be essential at present cigarette package film
The technical problem to be solved.Almost all of cigarette film producer put into a large amount of people according to the market demand in recent years
Power and financial resources remove the cigarette packing film of research and development superpower wear-resistant, but without the breakthrough for obtaining matter, from domestic and international tobacco business
From the point of view of collected cigarette film sample tests, product still reaches to want less than tobacco productive corporation in wear-resisting property application aspect
It asks.
Traditional cigarette package film product scratch-resistant performance is poor, easily produces during cigarette package with dynamic friction between machinery
Raw scratch, while the friction after logistics links vanning between the friction of item packet and parlor, item packet and corrugated case, sorting link
When friction can all generate scratch.In point-of-sale terminal, these scratches can cause visual adverse reaction, especially high-grade fragrant
Cigarette seriously affects the aesthetic feeling of original design, reduces the desire to purchase of consumer.In order to make up the not wear-resisting skill of cigarette film
Art short slab preferably shows the package design of cigarette in consumption terminal, and some tobacco factories, which are forced through in carton, increases plastic sheath
In friction or every cigarette between bag isolation cigarette and corrugated paper using the modes such as PE bag progress secondary packages reduce barrel and
Extraneous friction, but on the one hand these modes increase packing cost and workload, it is on the other hand palliative, in end pin
It sells link and still remains a possibility that product is scratched.
Summary of the invention
In consideration of it, the present invention provides a kind of packing film of superpower wear-resistant, meet all packets solving packing film product
Under the premise of installation type, the wear-resisting property of enhanced film makes it have the packing instructions for meeting cigarette product, to mitigate cigarette
The scratch that film generates during the packaging process and in logistics links makes cigarette package keep original design effect, enhancing consumption
The desire to purchase of person ensures the value dimension of cigarette product from the apparent visual of cigarette product.
The technical scheme of the present invention is realized as follows:
A kind of packing film of superpower wear-resistant, including three-layer co-extruded structure, the three-layer co-extruded structure are respectively upper layer, core
Layer, lower layer；The material for preparing on the upper layer includes high molecular polymer, nucleating agent, slipping agent, antiblocking agent；The sandwich layer
