Abstract

The invention discloses a method for making a highly weather-resistant and fragile label material, which includes the following steps: Q1: Select a non-corona-treated PET substrate with a thickness of 36 μm to 100 μm, and apply a weather-resistant coating on the surface of the PET substrate to obtain Composite film A and winding; Q2: Coating the color layer paint on the weather-resistant layer surface of composite film A to prepare composite film B and winding; Q3: Forming a covering layer on the surface of the color layer of composite film B to obtain a composite film C and rewinding; Q4: Coating the pressure-sensitive adhesive layer coating on the grid-shaped release paper or release film to obtain the composite film D; The sensitive adhesive layer is compounded to produce a highly weather-resistant and fragile label material. Through the above steps, the present invention can finally produce a highly weather-resistant and fragile label material, which has excellent chemical stability and physical properties, and meets high weather-resistant grade and fragile requirements, and has broad market prospects.

Description

technical field [0001] The invention relates to the technical field of label products, in particular to a method for making a highly weather-resistant and fragile label material. Background technique [0002] At present, fragile labels made of paper materials are widely used in the market, and paper fragile labels are widely used on the surface of machinery and equipment to play the role of identification and anti-counterfeiting, but there are major defects in the actual application process. If the paper fragile label is in the outdoor environment for a long time, the anti-counterfeiting effect will be greatly reduced due to its poor aging resistance. There are some fragile labels made of PVC on the market, but because the flexibility of the PVC material itself is too high, it cannot be fragile, and at the same time, the weather resistance level is low and it cannot be used outdoors for a long time, so the anti-counterfeiting effect is also low. It cannot meet the needs of ...
