Description
Technical field
The present invention relates to a kind of packaging bag composite material, particularly relate to the packaging bag composite material that a kind of suction pipe easily inserts.
Background technology
Common flexible package composite material generally is made up of printed layers, barrier layer, enhancement layer and sealing layer etc., and concrete structure is decided on the requirement of packing.Because printed layers and enhancement layer are selected biaxially oriented film usually for use, so the intensity of composite material is difficult for being torn and puncturing all than higher.The customer uses when the composite packaging bag of beverage is housed, and it is diffusing excessive that beverage easily takes place when tearing notch, brings very big inconvenience to the customer.A kind of packaged form that has socket is arranged in the market, it is the composite inner that is welded on pre-punching with the leakproofing material that a slice easily punctures, played the easily performance of puncture of good airproof performance, but owing to must just can realize at the specialized package make-up machine that has punching and seal, and need to increase extra auxiliary material, therefore be difficult for promoting the use of.
Summary of the invention
The objective of the invention is to provide a kind of be easy to insert suction pipe and reliable sealing beverage bag composite material, this beverage bag composite material can solve the problem of above-mentioned existence, and can apply widely, safe and reliable.
Composite material by adopting of the present invention two layers of material at least is composited, and one deck at least of above-mentioned composite material has pre-puncture socket, and with the one deck at least in the material of not doing above-mentioned pre-puncture in the above-mentioned composite material as sealing layer.
Above-mentioned beverage bag composite material can be made of two-layer, its cladding material is a kind of in biaxially oriented polypropylene film, biaxial stretching polyester film, biaxial tension nylon membrane, cellophane film, the two-sided moistureproof cellophane film, and inner layer material is a kind of in polyethylene film, cast polypropylene film, vacuum aluminum-coated cast polypropylene film, EAA, EMAA, co-polymer membrane, the multi-layer co-extruded polyethylene films such as EVA, SURLYN.
The beverage bag composite film material can constitute by three layers, its cladding material is a biaxially oriented polypropylene film, the biaxial stretching polyester film, the biaxial tension nylon membrane, cellophane film, a kind of in the two-sided moistureproof cellophane film, intermediate layer material is the aluminium film, the curtain coating nylon membrane, polyvinyl alcohol film, the EVOH film, the biaxial stretching polyester film, the biaxial tension nylon membrane, a kind of in the vacuum aluminum-coated polyester film, inner layer material is a polyethylene film, the cast polypropylene film, vacuum aluminum-coated cast polypropylene film, EAA, EMAA, EVA, co-polymer membranes such as SURLYN, a kind of in the multi-layer co-extruded polyethylene film.
The beverage bag composite material can constitute by four layers, its cladding material is a biaxially oriented polypropylene film, the biaxial stretching polyester film, the biaxial tension nylon membrane, cellophane film, a kind of in the two-sided moistureproof cellophane film, second layer material is the aluminium film, the curtain coating nylon membrane, polyvinyl alcohol film, the EVOH film, the biaxial stretching polyester film, the biaxial tension nylon membrane, a kind of in the vacuum aluminum-coated polyester film, trilaminate material is the aluminium film, the curtain coating nylon membrane, polyvinyl alcohol film, the EVOH film, the biaxial stretching polyester film, the biaxial tension nylon membrane, a kind of in the vacuum aluminum-coated polyester film, the 4th layer material is a polyethylene film, the cast polypropylene film, vacuum aluminum-coated cast polypropylene film, EAA, EMAA, EVA, co-polymer membranes such as SURLYN, a kind of in the multi-layer co-extruded polyethylene film.
The socket of beverage bag can connect the circular socket of cutting for circular socket or discountinuity.Also can connect a kind of in the criss-cross socket cut, U-shaped socket, the V-arrangement socket for criss-cross socket, U-shaped socket, V-arrangement socket and discountinuity.
The interlayer of composite material connects with adhesives, forms bonding coat.
In the present invention to the composite bed (functional layer) that is difficult for puncture in the complex film processing of puncturing in advance at the position of appointment, the size and dimension of pre-puncture socket can be adjusted according to the oad of different packing requirementss and suction pipe, and the sealing layer of commute puncture is not done to puncture in advance to handle.The result of Chu Liing has guaranteed that complex film still has complete packaging character like this, can reach the performance that easily punctures at the position of appointment again.Because its special pre-puncture is handled and is finished on final complex film finished product, thus on any type of automatic packaging machine or Bag Making Machine, all can use this product, and do not need to increase any special accessory equipment.
Novel suction pipe easily inserts the package compound film following three big characteristics
1, the customer is easy to use---and the functional layer of the difficult puncture in the complex film is the skin at packaging film, the processing of puncturing in advance, and iris out the pre-puncture processing region of appointment by printing, the customer can be easy to distinguish go forward side by side to exercise and use.
2, range of use is extensive---and it is to add in composite manufacturer to have finished pre-puncture processing man-hour that suction pipe of the present invention easily inserts complex film, therefore any package processing machinery processed routinely gets final product, and does not need to increase other any auxiliary material and equipment.
3, safe and sanitary is reliable---because pre-puncture is handled is a kind of mechanical treatment of physical property, does not add any objectionable impurities, and the complex film of compound mode and routine not have any mode different, so wholesomeness is safe and reliable.In addition, on the full wafer complex film, be complete as the in-to-in sealing layer, therefore suction pipe of the present invention easily inserts the liquid beverage that the package compound film still can effectively be protected packaging.
