The necessity of selecting starch adhesives
It would better choose starch adhesives to take the place of the synthetic resin adhesives which will benefit the cost savings. Starch adhesive owns the features of fast drying, strong bonding, environmental pollution, low cost and other fine features. In laminating, the ordinary carton adhesive, paper tube adhesive and paper pallets bonding, starch adhesive sealant can completely replace the synthetic resin adhesives.
The advantages of hot melt adhesives
In variety of adhesives, the drying time of hot melt adhesive is the shortest, for the adhesive molding process which needs instant drying and curing, and then it is advisable to use hot melt adhesive. Hot melt adhesive is ideal for bonding process between the plastic foam or EPE materials and paper, dry quickly, and the adhesive is very strong. We should note that the Heat Sink Paste has the most extensive range of application, but not for the adhesion of UV varnish paper products.
Different adhesives for different work
Due to the practices are different, the performance of the adhesives must also be different. Such as laminating process, the speed of the automatic laminating machine is fast, thus requiring lower viscosity adhesives and quick drying; while manual laminating machine is slow, thus requiring slightly fast of adhesive viscosity and drying speed should not be too fast.
The storage period of adhesive
The storage period should also be taken into consideration range when purchasing the adhesives. Storage period refers to under specified conditions adhesives stored, to stable performance maintain time. Purchases should be based on the enterprise's production situation to make sure the adhesives minimum storage period. For general corporate, the adhesives shelf life should be more than a month.
Adhesives for the different purposes of products
Usually the paper container requires only a sufficient adhesive strength in storage during the transport, while for the packaging of food, cosmetics and pharmaceuticals, except the adhesive strength requirements, and also requires the adhesives used must be odorless, non-toxic, in line with national health and safety regulations and environmental requirements. Certain ingredients, such as adhesive promoting agents, plasticizers, antioxidants, etc. may be transferred to the inner surface of the packaging material and contamination of food, which must be limited. In addition, it should be based on the specific use of paper products, adhesives various patience visits, such as heat resistance, water resistance, chemical resistance, aging resistance, low temperature resistance.
The security of adhesives
Environmental protection and safety are also the factors to be considered for adhesives. The solvent-based adhesives use large amounts of organic solvent, which not only serious pollute environment, but also damage to human health, and may cause a fire, and therefore should be possible to find a water-based or solvent-free adhesives.

Thanks to the seven-year arduous pioneering, Conor has marched into the stage of rapid development. Confronting to the domestic competition of adhesive, the company takes slow and steady efforts to catch up and now it has created a well-known brand among the domestic adhesive industry. The whole company will tenaciously strive to enter into the top 100 of the domestic adhesive industry.
