Embodiment 1

[0023] Example 1. (Production of transparent safety tape)

[0024] on figure 1 The production of transparent safety tape is based on a polyester film with a thickness of about 0.025mm as a matrix layer, and a thin layer of acrylic resin with a thickness of about 0.01mm is coated on the upper surface of the matrix layer as a hard resin layer. Coat the surface of the hard resin layer with low-molecular-weight wax as an anti-adhesive layer, and the coating amount is about 0.1gm / m 2 . Then, a thin layer of water-based acrylic adhesive with a thickness of about 0.01 mm is coated on the bottom surface of the substrate layer as an adhesive layer.

Embodiment 2

[0025] Example 2. (Manufacture of writing safety tape)

[0026] Repeat the steps of Example 1, but add a printing and writing layer. The printing and writing layer is sandwiched between the hard resin layer and the anti-adhesion layer. The Yinwei writing layer is a thin layer composed of a mixture of acrylic resin and calcium carbonate, wherein the weight ratio of acrylic resin to calcium carbonate is about 100:1. The thickness of the printing and writing layer is about 0.01 mm.

Abstract

The easy-to-cut safe adhesive tape includes a substrate layer, a hard resin layer, an adhesive layer and a non-adhesive layer. The substrate layer is plastic film, the hard resin layer is applied to the substrate layer to regulate structure property, the adhesive layer is applied to the bottom surface of the substrate layer and the non-adhesive layer is applied to the surface of the hard resin layer for peeling effect. With the hard resin layer to regulate the physical property, the adhesive tape is easy to cut and safe.

Description

Technical field [0001] The present invention relates to an adhesive tape, in particular to a safety adhesive tape that is easy to cut and tear and is more convenient for consumers to use. Background technique [0002] Adhesive tape has been used as a packaging material for a long time. Generally, the tape used in packaging or daily use generally includes a matrix layer, an adhesive layer and an anti-adhesive layer. In general needs, the matrix layer emphasizes sufficient tensile strength (tensile strength) or elongation (elongation), so the material has high toughness, relatively in consumer use occasions, its cutting or tearing is also relatively high. inconvenient. [0003] Taiwanese Patent No. 106921 (Application No. 84206837) owned by the inventor provides tapes that can be used for writing. In addition to printing text, patterns or writing, it can be pasted at will. Summary of the invention [0004] In view of the shortcomings in the use of tape substrates in the past, the ...
