Thirteen.Skinning There are two common skin phenomena: one is in the packaging bucket of glue surface skin, the other is in the glue tray surface skin. ■ The surface layer of glue in the packing bucket produces crusts 1)If the temperature of glue filtration packaging is too high, it is easy to form crust in the barrel when the temperature drops, which is common in high temperature in summer. Becau...
Eight, filling The concept of filling is rarely mentioned in the application of laminating glue, but can never be ignored.The surface of the paper inevitably exists in some depression. When compounding, if the depression in the paper cannot be fully filled, it will also cause the weak. (Excellent filling effect) &nb...
Anti -deformation power Anti -deformation capacity refers to a certain deformation after the composite product is affected by external forces, and this deformation will produce a certain amount of elasticity, especially the thin film. If the combination of composite is not enough to resist the elasticity of the return, foaming will occur, etc. Happening. There are many processes that produce defor...
Bond strength and deinking Bond strength is one of the most important indexes of glue properties. Bond strength refers to the amount of force required when the film and paper are stripped, and this index is often combined with the deinking effect. We first need to understand the principle and structure of paper-plastic composite. If you want to enhance the bonding force, you must consider the...
The relationship between the index of laminating glue and common problems I. Viscosity Viscosity is the internal friction of the liquid, and colloquially, the thin consistency of the glue. The viscosity of the glue does not indicate the bonding performance of the glue, in other words, the thicker the glue is, the better the performance is. The viscosity can be adjusted within a cert...
Hot melt adhesive (English name: HotGlue) is a kind of plastic adhesive, in a certain temperature range, its physical state changes with the change of temperature, but the chemical properties remain the same, its non-toxic and tasteless, belongs to environmental protection chemical products.Because the product itself is solid, easy to package, transport, storage, no solvent, no pollution, non-toxi...
Protective film glue transfer, there are a variety of factors, I believe that in the work, many teachers will also encounter a similar situation.The phenomenon of the so-called glue transfer is uneven coating or in the process of transportation, the glue shift remains on the surface of the profile, commonly known as glue transfer. Protective film glue transfer can be divided into the followin...
Water-based glue, when the autumn and winter season, special attention should be paid to anti-freezing treatment, according to different temperatures, the implementation of different solutions. Cautions (1) Pay attention to warmth and anti-freezing when transporting glue: when transporting below 0℃, pay attention to the warmth of the vehicle, and transport below -5℃ is prohibited; (2) Ke...
Label is used to show the relevant instructions of the product of the printed matter, some are on the back of the glue, but there are some printed matter is not with glue, glue label is known as "self-adhesive label". Self-adhesive label is a kind of material, also called self-adhesive material. It is a composite material made of paper, film or other special materials, coated with adhesive on...
Sixteen common types of self-adhesive labels This paper introduces sixteen types of self-adhesive labels commonly seen in daily life. The specific types of self-adhesive labels are as follows： 1. Press smooth writing paper and offset paper labels Multi-purpose label paper for information labels, bar code printing labels, especially suitable for high speed laser printing, also suitable fo...
