Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the accompanying drawings and examples, which are not intended to limit the present invention.

As shown in fig. 1, an embodiment of the present invention includes a sheet body including a printing layer 1, a plastic sheet layer 2, a heat-sealing layer 3, and an adhesive layer, the printing layer 1 being disposed on an upper end of the plastic sheet layer 2, the plastic sheet layer 2 being disposed on an upper end of the heat-sealing layer 3, the adhesive layer including a first adhesive layer 4 and a second adhesive layer 5, the printing layer 1 being fixedly connected to the plastic sheet layer 2 through the first adhesive layer 4, and the plastic sheet layer 2 being fixedly connected to the heat-sealing layer 3 through the second adhesive layer 5. Wherein, the printing layer 1 is a polyester film, the polyester film is a modified ethylene terephthalate layer, the plastic sheet layer 2 is a modified polyvinyl chloride layer or a modified polystyrene layer, and the heat sealing layer 3 is a modified polyethylene layer.

In this embodiment, through the modified sheet of screening difference, after automatic packaging machine uses, blow not broken and the shaping is effectual, and heat-seal strength is appropriate, and the heat-seal face is smooth, does not have wire drawing fluff phenomenon. Wherein the plastic sheet in the middle layer is a blow molding part, and the screened sheet has the advantages of low temperature resistance, stretch resistance and good molding effect. Wherein, the plastic sheet can be modified polyvinyl chloride or modified polystyrene.

In the embodiment, the heat-sealing layer 3 is modified easy-to-tear polyethylene, the selected polyethylene has good heat-sealing effect and moderate heat-sealing strength, and the polyethylene is torn off after heat-sealing, so that the heat-sealing surface is smooth and has no phenomena of wire drawing and fuzzing.

In this embodiment, the sheet body is composed of three layers bonded together, and the three layers are a polyester film, a plastic sheet layer 2, and a modified easy-to-tear polyethylene layer in sequence from outside to inside.

In this example, the following steps are required to prepare the composite sheet:

firstly, printing pictures, texts and patterns on a plastic film by a printer to form an ink layer on the plastic film, and preparing a semi-finished product;

secondly, compounding the polyester film and the plastic sheet layer 2 into a whole by a dry compounding machine through an adhesive in sequence, and immediately curing for 1 hour to obtain a compounded semi-finished product;

and thirdly, compounding the semi-finished composite product and the modified easy-to-tear polyethylene film into a whole by using an adhesive through a dry compounding machine, curing for 36 hours, and cutting to obtain a finished product.
