How important are high-temperature resistant labels?
This is a label that can be used under extreme temperature conditions. Electronic products generate heat during operation, and some products may also be placed in high-temperature environments for use. The high-temperature resistant label ensures that the label information of the product remains clear and visible under all these conditions, thereby ensuring the effective transmission of safety information and warning signs. This not only reflects the product's emphasis on safety, but also subtly strengthens consumers' trust in the brand.
Structure and Application Fields of High Temperature Resistant Labels
High temperature label paper, also known as high-temperature resistant label paper, high-temperature resistant label paper, high-temperature self-adhesive label paper, steel high-temperature resistant label paper, etc., may have different names in different industries
High temperature resistant label paper is made of polyimide film as the substrate and coated with special pressure-sensitive adhesive. It has good chemical resistance and wear resistance, and can withstand temperatures up to 320 ℃. It has a certain anti-corrosion effect on chemical substances such as flux, melting agent, and cleaning agent, and can maintain excellent performance when used in high temperature and harsh environments. There are three main parts: substrate, adhesive, and substrate
01. Substrate
25um (or 50um) coated polyimide films without coating treatment cannot meet performance requirements. Coating treatment can better meet the process requirements for printing barcodes, QR codes, and material color and glossiness
02. Adhesive
Nowadays, adhesives are generally divided into three categories: rubber, acrylic, and silicone. Rubber adhesives have low cost, poor temperature and chemical resistance, and outstanding aging resistance. Silicone adhesives have superior performance, but outstanding are expensive. Acrylic adhesives have a temperature resistance of about 200 degrees and good chemical and oxidation resistance. Currently, some brands of adhesive tapes use acrylic adhesive with 90% of their adhesive properties. The high-temperature resistant label paper adopts Yong long-lasting acrylic pressure-sensitive adhesive
03. Substrate
Gracin release paper, white single copper release paper, silicon yellow release paper, PET release film, transparent release paper (commonly used for automatic labeling, easy to peel off without damaging the bottom) Automatic labeling high-temperature resistant label paper saves labor and provides efficiency
Heat transfer barcode paper
The lowest level in the evaluation grade of the curve parameters obtained from barcode detection (minimum edge ratio, decoding performance, stripe contrast, decoding ability, defect degree) is the grade of the curve. The levels of each parameter and the scanning reflectance curve are represented by letters A, B, CD, and F, corresponding to 4, 3, 2, 1, and 0 in the national standard, respectively. The national standard requires symbol levels not to be lower than 1.5/10/670
A-level barcode corresponds to symbol quality level: 4.0-3.5:
B-level barcode corresponds to symbol quality level: 3.4-2.5
C-level barcode corresponds to symbol quality level: 2.4-1.5:
D-level barcode corresponds to symbol quality level: 1.4-0.5
Heat transfer paper is a type of powder coated copperplate paper that has undergone special powder surface treatment and has a glossiness below 20 degrees. The paper is soft and elegant, with a matte effect, a refreshing and comfortable visual experience, and high non reflective opacity. It has excellent color saturation and vividness, and has excellent texture and ink absorption performance. It is suitable for heat transfer printing of various high-definition and high-density barcodes, and is suitable for most wax based and mixed based carbon tapes (recommended Ricoh B110A). It can easily print A-level barcodes
Heat Resistant Label
High temperature labels are made of polyimide film as the substrate and coated with special pressure-sensitive adhesive, which has good chemical resistance and wear resistance. They can withstand temperatures up to 320 ℃ and have a certain anti-corrosion effect on chemical substances such as flux, melting agent, and cleaning agent. They can maintain excellent performance in extremely harsh environments with high temperature and wear.
It is designed specifically for character or barcode labels on printed circuit boards, as it can withstand the erosion of soldering agents, melting agents, etc. encountered during the production of printed circuit boards. At present, there are mainly two thicknesses: 25um and 50um. The commonly used colors are black and white. High temperature resistant label stickers are widely used in SMT and peak processing of numerous electronic products, motherboards, corrosion products, mobile phones, and lithium batteries for high-temperature resistant labels.
In order to avoid printing failures of high-temperature labels caused by quality issues of the high-temperature materials themselves as much as possible, it is necessary to carefully inspect the appearance quality of the high-temperature materials before printing, so that defects that may cause printing quality problems can be detected in a timely manner before printing.
High temperature resistant labels are mostly used in special industrial environments, such as SMT circuit board mounting, MES, hot rolling steel in the steel industry, aluminum industry, pottery and other industries; As a carrier of barcodes and text for users who want to achieve visual identification, barcode automation management, and quality traceability in production processes, it not only needs to be resistant to high temperatures, but also needs to have characteristics such as chemical corrosion resistance, friction resistance, and super strong viscosity in special environments. Can be used for barcode printer heat transfer printing, trademark machine and rotary printing, etc
