Abstract
The utility model discloses a multi-functional heat-sealing film. The multi-functional heat-sealing film is provided with a base layer film, wherein a printing layer is printed on inner surface of the base layer film; an inner layer film is composited on the inner surface of the printing layer through an adhesive layer; and a heat-sealing layer is formed on the inner surface of the inner layer film through coating heat-sealing adhesive. The heat-sealing adhesive coated on inner layer of the multi-functional heat-sealing film is waterborne polyurethane heat-sealing glue which has the following advantages: 1. heat-sealing intensity is high, and the heat-sealing intensity of the heat-sealing film and a PVC sheet can be stabilized within 8-15N/15mm; 2. sealing beginning temperature is low, the heat-sealing film can be heat-sealed at the temperature of 130 DEG C, and optimum heat-sealing temperature range is 130 DEG C to 150 DEG C; 3. the multi-functional heat-sealing film can heat seal both the PVC material and APET material; and 4. the coated waterborne polyurethane heat-sealing glue is safe and environmental-friendly.
Description
Technical field
The utility model relates to a kind of compound package material, particularly a kind of multi-functional heat-sealing film for heat-sealing PVC and APET material.
Background technology
The material that is used for sealing with the PVC sheet material in the packaging material at present mainly is the PTP aluminium foil.Have some polarity plastic sheetings also can seal with the PVC sheet material by applying one deck heat-sealing adhesive, but its heat seal strength is often lower; And at the PE(polyethylene) etc. on the non-polar plastic film many adhesives often be difficult to apply or adhesive force extremely low.These materials often are difficult to satisfy protection and the iris action to the packing content thing.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, has proposed a kind of multi-functional heat-sealing film rational in infrastructure, high heat-sealing strength.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of multi-functional heat-sealing film, be characterized in: be provided with base film layer, be printed on printed layers at the base film layer inner surface, the inner surface of printed layers is compounded with inner layer film by adhesive phase, and the inner surface of inner layer film forms hot sealing layer by applying heat-sealing adhesive.
The technical problem to be solved in the present invention can also come by the following technical programs to realize that further described base film layer is polyester film, PA membrane, biaxially oriented polypropylene film or cellophane film that thickness range is 0.03-0.10mm.
The technical problem to be solved in the present invention can also come by the following technical programs to realize that further described adhesive phase is two component polyurethane adhesive that thickness range is 0.001-0.004mm.
The technical problem to be solved in the present invention can also come by the following technical programs to realize that further described inner layer film is low density polyethylene films or density polyethylene film with high that thickness range is 0.02-0.06mm.
The present invention compared with prior art has following advantage: heat seal strength is high, and the heat seal strength of this heat-sealing film and PVC sheet material can be stabilized in 8-15N/15mm.It is low to play the envelope temperature, and this heat-sealing film is just heat sealable in the time of 130 ℃, and best heat-sealing temperature range is 130 ℃-150 ℃.Heat sealable multiple material not only can seal the PVC material, can also seal the APET material, and heat seal strength can be stabilized in 8-20N/15mm; Heat-sealing adhesive is aqueous polyurethane heat-seal adhesive water-based material, and safety and environmental protection also can have good compatibility with hydrophilic solvents such as ethanol.
Description of drawings
Fig. 1 is structure diagram of the present utility model.
The specific embodiment
A kind of for heat-sealing PVC(polyvinyl chloride) and noncrystallineization of APET(PETG) the multi-functional heat-sealing film of material.Be provided with base film layer 1, be printed on printed layers 2 at base film layer 1 inner surface, the inner surface of printed layers 2 is compounded with inner layer film 4 by adhesive phase 3, and the inner surface of inner layer film 4 forms hot sealing layer 5 by applying heat-sealing adhesive.
Described base film layer 1 is polyester film, PA membrane, biaxially oriented polypropylene film or cellophane film, and thickness range is 0.03-0.10mm.
Described adhesive phase 3 is two component polyurethane adhesive, and thickness range is 0.001-0.004mm.
Described inner layer film 4 is low density polyethylene films or density polyethylene film with high, and thickness range is 0.02-0.06mm.
Described heat-sealing adhesive is the aqueous polyurethane heat-seal adhesive, available water or ethanol dilution during use, and dried glue coating weight scope is 1.5-3.5g/m2.
100 ℃-120 ℃ of bake out temperatures during described heat-sealing adhesive coating, the time is 8-15 second.
