Embodiment 1

[0052] The first process:

[0053] (1) Substrate unwinding: Unwind the BOPP coil with unwinding equipment;

[0054] (2) Corona treatment: use corona treatment equipment to corona treat the inner side of the BOPP substrate, so that the inner surface tension coefficient reaches 42-46 dynes;

[0055] (3) Primer treatment: such as Figure 5 As shown, apply a layer of primer on the inner side of the corona treatment; the rubber roller is made of EPDM, and the ink-absorbing roller is made of mirror steel roller; the diameter of the rubber roller is 180mm: the diameter of the ink-absorbing roller is 230mm; the primer The agent is AC agent;

[0056] (4) Drying treatment: pass the BOPP base film coated with the primer through an oven, and dry under sealed conditions; the drying temperature is 55 ° C, and the drying time is 3 seconds;

[0057] (5) Composite processing: such as Figure 2~4 As shown, first put the EVA resin particles in the extruder, heat the extruder and adjust the s...

Abstract

The invention relates to the technical field of packaging materials, in particular to a preparation technology for a BOPP tactile mercerized film. According to the preparation technology, through thefirst working procedure of corona treatment to the inner side of a substrate as well as primer treatment, drying treatment, compound treatment, corona treatment and the like, and then through the second working procedure of corona treatment to the outer side of the substrate as well as oiling treatment, drying treatment, cooling treatment, corona treatment and the like, the finished BOPP tactile mercerized film is obtained; and the BOPP tactile mercerized film comprises an EVA cast film, a primer coating, a BOPP matt film and a water-based tactile oil layer, and has special smooth and delicatesense of touch like velvet, and the performances are excellent.

Description

technical field [0001] The invention belongs to the technical field of packaging materials, in particular to a preparation process of a BOPP tactile mercerized film. Background technique [0002] BOPP film is widely used in the field of packaging due to its colorless, odorless, non-toxic properties, as well as excellent tensile strength, impact strength, toughness and transparency. In life and business activities, people have higher and higher requirements on the quality of gift packaging, especially the packaging of high-end gifts and high-end electronic products. The feeling of hand touching the packaging material is the first feeling for gifts, and a good touch will make people feel good, but at present, there are few reports on the research on the tactility of the surface of BOPP film. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a preparation process for a BOPP tactile mercerized film. [0004] The present in...
