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 adhesive is coated on the PE roll film at an interval of 10.5m to form an adhesive film 2, and each non-adhesive film 1 and an adhesive film 2 are a packaging segment , that is, semi-finished packaging materials 4 with 10.5m non-adhesive films and 8.5m adhesive films arranged at intervals are obtained; the length and width of the packaging materials can vary according to the size and shape of the items to be packaged and the packaging purpose.

[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 2 and the non-adhesive film 1 of the adjacent packaging section;

[0029] Such as image 3 As shown, a U-shaped double-sided adhesive tape 6 is bonded between the cut non-adhesive film 1 and the adhesive film 2, and the double-sided adhesive base layer 6D is bonded on the sid...

Abstract

The invention aims to provide an automatic packaging roll film and a preparation method thereof. According to the roll film, sticky regions (2) parallel to one another are formed in the transverse direction of the same side of a roll film base material at intervals; a non-sticky region (1) is formed between two adjacent sticky regions (2); each non-sticky region (1) and an adjacent sticky region (2) form a packaging section; between adjacent packaging sections, the non-sticky region (1) of the previous packaging section and the sticky region (2) of the latter packaging section are connected through a separable adhesive tape; and all packaging sections are connected through the separable adhesive tapes so as to form an integral continuous automatic packaging roll film (3). According to the automatic packaging roll film provided by the invention, the technical problem that automatic packaging fails due to film clamping and breaking even shutdown occurring in the automatic packaging process is solved.

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 ...
