Because of a wide variety of adhesive materials, it is now widely used in different fields.
The self-adhesive label is also called self-adhesive label, instant paste, instant paste, etc. it is a composite material which is made of paper, thin film or special material, coated on the back and coated with silicon substrate, and processed by printing and die cutting. There are a wide variety of adhesive materials, which have been widely used in different fields.
Often users advisory said label stickiness is not firm, the reason is complex, some unknown to the customer, also said the material quality problems, in fact, the material there is no quality problem, but there may be no clear customer viscous requirements, or not in large quantities of paste before, try to stick experiment. Therefore, may lead to viscosity did not achieve the desired requirements, all the surplus metal with many years of experience are the crux of the problem are put together:
The cause analysis and Countermeasures of the edge of the label, the tabs, the folds and the folds
1. labeling pressure is too small or poor contact: check the manual labeling process or automatic labeling process to paste;
Improper selection of 2. surface materials: exchange of thin or soft surface material;
3. base material surface residue chemical or wet: pay attention to cleaning process and drying before packing material labeling;
4. temperature or temperature is not suitable for labeling: note that the choice of adhesive properties, avoid low temperature operation;
5.: pay attention to the choice of adhesive improper selection and use of supplier product recommendation.
Two. Analysis and Countermeasures of the cause of small caliber tag lifting or 90 degree right angle arch
Improper selection of 1. surface materials: exchange of thin or soft surface material;
2. improper selection: 3 cm diameter adhesive label following small caliber and small package and 90 rectangular design consultation and do the experiment first label.
Three. Analysis and Countermeasures of the reasons for the falling off / non stick of the label
1. unsuitable storage conditions before the use of the label causes failure: pay attention to the supplier's product storage and warranty period;
2. wet, rough or residual chemicals on the surface of the base material: pay attention to the cleaning process and drying before the packing material is labelling;
3. improper selection of adhesives: pay attention to the selection and use of the supplier's products.
Four. Analysis and Countermeasures of the cause of flying mark or no mark in automatic labeling
The stripping force is too low / too high: according to the automatic labeling speed and the selection of qualified supporting materials.
In addition, the adhesive label will affect the use effect because of the material quality and the printing process, and choose the high quality label as far as possible.
