Abstract
The utility model discloses a paper molding composite structure, comprising a paper layer and a plastic film layer heat-sealed on the paper layer. The utility model is characterized in that the paper molding composite structure is in a double layer structure formed by directly compounding a cementless coextruded twinning axis stretched polypropylene (BOPP) film to the surface of a paper layer. The surface of the twinning axis stretched polypropylene (BOPP) film is provided with a functional layer after coextrusion and graft modification treatment, realizing direct compounding of the cementless coextruded BOPP film with the paper layer. The paper molding composite structure is of no need to change a current paper molding composite device ( a laminating machine); the racking strength of the paper molding composite materials is stronger than the strength of the paper, thus improving work efficiency and meeting the requirements of environment protection.
Description
Technical field
The utility model relates to plastic sheeting and the compound technical field of paper.
Background technology
At present the general compound way of paper has: the one, adopt glue method (doing multiple or wet multiple), and promptly adopt online gluing (adhesive) and compound, thereby tend to airborne release toxic solvent serious environment pollution when adopting the glue method with paper hot pressing; Second kind is precoating method, promptly adopts pre-coating film to carry out hot pressing, and it is to spoon one deck thermal synthesis layer and compound with paper hot pressing above the film at biaxial stretch-formed polypropylene (BOPP); Though precoating method can need many procedures without solvent, it is more to increase cost.Above-mentioned two kinds of compound ways of paper all are to utilize the pore and the polarity of paper, are three-decker.Also have certain methods as drenching embrane method, directly polyethylene is drenched above the paper, the method is in a ratio of diverse ways with aforementioned two kinds, and used plastic material is difference also.
Summary of the invention
The purpose of this utility model is to provide at the deficiency of above-mentioned paper composite construction a kind of toxic gas, combined strength bination height, easy environment-friendly paper plastic composite structure of processing of not producing under the prerequisite that does not change existing paper equipment complex (laminating machine).
For achieving the above object, the utility model has adopted following technical scheme: a kind of paper composite construction, comprise papery layer and the heat seal plastic film layers on the papery layer, it is characterized in that, this paper composite construction is a double-layer structure, directly is compounded in the papery laminar surface by the no glue composite membrane of biaxial stretch-formed polypropylene (BOPP) and constitutes.
Adopt the beneficial effect of said structure to be; because the utility model has only adopted double-layer structure; its plastic film layers is biaxial stretch-formed polypropylene (BOPP) film that surface functional layer has adopted MODIFIED PP; thereby biaxial stretch-formed polypropylene do not have the glue composite membrane with its function face directly and stationeries such as offset paper, art paper compound; thereby protection paper or paper printing face also obtained high glaze or the effect of mute light, and its major advantage is embodied in following aspect:
1, need not change existing paper equipment complex (laminating machine), can be directly bonding with paper under existing process conditions, use that this product and paper are compound need not do any adjustment to having the paper laminating machine now.
2, compliance with environmental protection requirements, compare with traditional handicraft and structure, plastic sheeting need not online gluing or pre-gluing, save the glue in traditional paper combination process, thereby thoroughly eliminated of the harm of poisonous volatile matter, also avoided the potential hazard of traditional paper joint product the consumer to labourer and environment.Attachment function layer of the present utility model is realized in filming technology by the biaxial stretch-formed method of coextrusion.
3, improved efficiency, save the gluing program in glue method and the precoating method, combination process is more simple, thereby increases work efficiency, reduces labour intensity and protection labourer and environment.
4, the peel strength of composite paper-plastic material is greater than paper wood body intensity.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, paper composite construction of the present utility model is that papery layer 1 and plastic film layers 2 double-layer structures of heat seal on papery layer 1 constitute, and plastic film layers 2 is the no glue composite membrane of biaxial stretch-formed polypropylene (BOPP), and its surface is a functional layer, is MODIFIED PP.
Functional layer of the present utility model adopts is extraordinary heat-sealable material through graft modification, and the direction of modification is low temperature properties and high polarity, makes material modifiedly both to have good cohesive with PP, has good heat sealer with paper again.The no glue composite membrane of the utility model biaxial stretch-formed polypropylene (BOPP) is that the compound industry of BOPP paper has been opened up not only environmental protection but also economic new film kind.
