Embodiment 1

[0027] Such as figure 1 As shown, a 2700mm PE film is produced by a three-layer co-extrusion casting machine, and 8.5m of glue is coated on the PE roll film at an interval of 10.5m to form a sticky film. Each non-sticky film and a sticky film are a packaging section, which can be obtained 10.5m of non-adhesive film and 8.5m of adhesive film are semi-finished packaging materials arranged at intervals 4; the length and width of the packaging material can vary according to the size and shape of the items to be packaged and the purpose of packaging.

[0028] Such as figure 2 As shown, put the semi-finished packaging material 4 into the rewinder, and cut the joint between the adhesive film and the non-adhesive film of the adjacent packaging section;

[0029] Such as image 3 As shown, the U-shaped double-sided adhesive tape 6 is bonded between the cut non-adhesive film and the adhesive film, and the double-sided adhesive base layer 6D is bonded on the side end of the non-adhesiv...

Abstract

The object of the present invention is to provide an automatic packaging roll film and a preparation method thereof, wherein the roll film is provided with mutually parallel adhesive zones (2) at the lateral intervals on the same side of the roll film substrate, and the adjacent two adhesive zones (2) A non-adhesive area (1) is formed between them, and each non-adhesive area (1) and an adjacent adhesive area (2) are a packaging segment; between adjacent packaging segments, the non-adhesive area (1) of the previous packaging segment ) and the adhesive area (2) of the following packaging section are connected by a separable adhesive tape; each packaging section is connected by a separable adhesive tape to form a continuous automatic packaging film (3) as a whole. The present invention solves the technical problem of film jamming, film breaking and shutdown caused in the automatic packing process, thereby causing automatic packing failure.

Description

technical field [0001] The invention relates to packaging materials, which belong to the field of chemical materials, and in particular to an automatic packaging roll film and a preparation method thereof. Background technique [0002] The main advantage of roll film applied to the packaging industry is to save the cost of the entire packaging process. The application of roll film to automatic packaging machinery does not require any edge banding work by the packaging manufacturer, only a one-time edge banding operation in the manufacturer is sufficient. The emergence of roll film simplifies the entire process of plastic packaging into three major steps of printing-transportation-packaging, which greatly simplifies the packaging process and reduces the cost of the entire industry. [0003] At present, the automatic packaging roll film is generally made of two or three layers of materials co-extruded and compounded, and different material structures can be matched according ...
