Double adhesive paper refers to paper that paint the rubber on the two sides of the paper during the papermaking process to improve its surface material.Double adhesive paper has small telescopic properties, uniform absorption of ink, good smoothness, tight and non -transparent texture, and strong water resistance.Generally, the quantity of double rubber paper is between 60 grams and 120 grams, and 150 grams of high grams of high -grams double gel paper.In the fax paper, double rubber paper and copper paper are very similar, in fact, it is easy to distinguish from the material.But what exactly is double adhesive paper? Lets take a look at the details together.
What is double adhesive paper
Double adhesive paper: refers to the paper that applies the rubber on the paper on the two sides of the paper during the papermaking process to improve the surface of the surface.Generally, the quantitative double rubber paper is between 60 grams and 120 grams, and there are 150 grams, 180 grams, and 300 grams of high grams of high-grams of double rubber paper; of which 70-120 grams of double rubber paper uses the most widely.Those who are less than 60 grams are not called double glue and are called writing paper. Writing is a relatively poor paper species.
What are the common number of double adhesive paper grams?
1. Double gum paper grams: grams, also called gram heavy, refers to the weight of 1 square meter area of ??paper, usually the unit is G/m2 or GSM (gram/square meter).In paper measuring, the professional terms of gram are quantitative.
3. Flat paper (flat) specifications: 787 × L092 mm; large degree 850 × 1168 mm, etc.Roll paper specifications: 787 mm, 1092 mm, 850 mm, etc.
The difference between glue paper and copper version paper
Double adhesive paper and copper paper are mainly material.Copper paper is made of high -density fibers (cotton, bark, etc.), and double rubber paper is made of low -density fiber (grass slurry, etc.).The same thickness, the weight per square meter is completely different.Due to the level of chemistry, it is sometimes difficult to distinguish.The best way: tear the paper, the copper version of the paper is tough, and the double gel paper is very loose (crispy).Moreover, the fiber of double rubber paper is thick.
