The difference between copperplate paper and regular paper in adhesive materials

The main difference between copperplate paper and regular paper in adhesive materials is their different uses, weights, and appearances. Simply put, the difference between the two is that copperplate paper has adhesive on both sides, while regular paper does not. The original paper that is similar to copperplate paper is uncoated copperplate paper

The actual difference between copperplate paper and regular paper in stickers

1、 The weight varies, with copperplate paper weighing around 100-450 grams and regular paper weighing around 180-300 grams

2、 The appearance is different, and the flatness and milky white color of copperplate paper are higher; The demand for regular paper is not that high

3、 The main uses are different. Copperplate paper is mainly used for printing color pages, advertising, packaging, etc. Copperplate paper has a unique coating that can package and print vibrant colors, while regular paper is generally used for book printing

4、 The processing technology is different. Copperplate paper is made by using bleached chemical wood pulp or partially bleached chemical straw pulp on a paper machine. Writing paper is made from bleached chemical paper pulp as raw material, copied by a long or round net machine, and polished

Why

Does temperature have an impact on adhesive labels?

Some customers often report that the adhesive strength of self-adhesive labels is insufficient, resulting in the detachment of product labels. In the food industry, such issues are particularly prominent. On a common product label, the description of the ambient temperature is as follows: maintain room temperature, applicable ambient temperature range is -50 ° C to 80 ° C, and the minimum ambient temperature on the product label is 7 ° C. There are three types of environmental temperatures mentioned here, namely storage environment temperature, labeling environment temperature, and application environment temperature. Next, we will explore the significant impact of environmental temperature on product labeling

Adhesive labels are affected by surrounding moisture, coupled with temperature changes in the morning and evening, and repeated use can cause label deformation. However, professional low-temperature resistant adhesive labels can withstand extreme environmental temperatures and temperature changes, and are suitable for all refrigerated storage products

Refrigerated food labels can have a significant impact on the quality of adhesive labels during cold and humid weather. What are the consequences of using adhesive labels in an environment with temperatures below minus tens of degrees? What kind of product labels should we choose

The characteristics of a cold storage environment are high humidity and low temperature. If ordinary product labels are used in cold storage, the labels are prone to deformation, wrinkling, and detachment. In addition, there are various forms of packaging for items inside the cold storage. Therefore, the selected product labels should have excellent waterproof, moisture-proof, and low-temperature resistance performance

There are various types of adhesive for product labels, and ultra-low temperature adhesive should be used in cold storage. If the label is attached at room temperature and then placed in the cold storage, the label paper should be made of a material with obvious elasticity. Considering that the packaging form of the item may be ordinary paper packaging or nylon bag packaging, different materials of product labels can be selected according to the needs

What is UL/CSA certification for adhesive materials?

What is UL/CSA certification for adhesive materials? What issues should be noted when printing

1. DUL/CSA label. Certified labels refer to label products that can withstand special conditions and ensure absolute information security on the label, such as installation instructions, power data, warning symbols, caution symbols, etc. The information on the label will involve the safety of the final product, requiring that this information be identifiable for a long time and retained on the product for a long time

2. UL/CSA label materials. UL/CSA label material certification refers to the quality certification of products produced by label material manufacturers, including the surface material of blank labels, point bonding for composite use, and surface composite materials. The processed label materials are sold in roll form to label processors for label production. When label processors use ULL/CSA label materials, they can receive discounts on the transfer of certified materials from the material manufacturer, and can directly produce UL/CSA certified label products using such materials

3. UL/(SA Ink. Ink is part of UL/CSA labels. The ink used by label processors is specified in the manual developed by ULCSA. Only these specific oils # can be used to print UL/CSA certified labels. Generally, material manufacturers must undergo UL/CSA testing for the ink used in certified materials and recommend qualified ink to label processors for reference. Label processors can use the ink recommended by tui and matching materials to directly organize production.

4. UL/CSA label processor. ULCSA label processor refers to a label processor that is qualified to produce one or several UL/CSA label products. The information of UL/CSA label manufacturers can be found in the corresponding manuals< br/>
The labels produced by ordinary label processors using UL/CSA certified materials and inks are not UL/CSA labels. Because the first regular label processor does not have the qualification to produce UL/CSA labels; Secondly, the materials and inks used may not necessarily match, and processors can purchase the above materials from different suppliers, such as printing materials and laminating materials purchased from both sources

UL/CSA label manufacturer. Obtaining UL/CSA label processing qualification means that the processor submits the certification documents of certified materials, inks, etc., as well as the label products printed using them, to the relevant UL/CSA agencies and submits an application. After passing the UI/CSA inspection, a production and processing qualification certificate for a certain label product will be issued to it. Label processors will use these materials to produce UL/CSA labels for customers on a fixed basis

What are the specific types of PVC adhesive materials?

PVC adhesive material, like PET adhesive, is also a type of polymer material. The common colors of PET materials include matte silver, bright silver, bright gold, sub white, bright white, sub black, and bright black. Unlike it, PVC adhesive materials come in a wide variety of colors, which can be said to be colorful. Let's get to know each other in detail together.

The common colors of PVC label materials include sub white, pearl white, and transparent. PVC adhesive and PET adhesive labels have similar performance, with better flexibility and a soft touch than PET label paper. They are often used in high-end occasions such as jewelry, watches, electronics, and metal industries. However, the degradation of PVC label materials is poor, which has a negative impact on environmental protection. Some developed countries abroad have begun to develop alternative products in this area.

PVC (polyvinyl chloride) has two types: soft and hard, with good durability, tear resistance, flexibility, and chemical corrosion resistance. It is widely used in electronics, machinery, batteries, and outdoor applications. But the temperature resistance and tensile strength are generally average, and there will be a certain degree of shrinkage under the influence of temperature. Easy to tear off when stretched. Due to environmental restrictions, indoor use is becoming increasingly rare.

The commonly used thickness of PVC is 80u, and different adhesives can be used according to different application needs. There are water-based glue, hot glue, oil-based glue, removable glue, etc. The base paper can be paired with Grassin base, white thick base, etc.
