①BOPP / VMCPP
The composite structure is mainly used in the field of light food packaging such as instant noodles, egg yolk pie and snow cake. The composite structure is most suitable for one-component aqueous adhesives. Compared with solvent-based polyurethane adhesive, single component water glue less ink transfer phenomenon, and the initial adhesion is high, without aging, can be directly cut bag process.
② BOPP/CPP
This structure is more suitable for the use of two-component water glue, and the bonding strength of single-component water glue can not meet the requirements of use. The structure is also mainly used in bread, cake and other packaging.
③ PET/VMCPP
This kind of structure is mainly used in candy, back - sealed rice cake packaging. The single-component water glue is more suitable for this structure, which can effectively control the transfer of aluminum plating and meet the requirements of high-speed packaging.
④ PET(BOPP)/VMPET/PE
The water-based adhesive can be used in this structure twice. The outer composite can effectively reduce the transfer of aluminum plating and provide sufficient bonding strength. The inner composite can effectively avoid the influence of friction coefficient on bag making.
⑤PA/PE, PET/PE and BOPP/PE
The above three structures are more suitable for the use of two-component aqueous adhesives. Due to the good low temperature resistance of waterborne adhesive. It can make the above three structures in the frozen food packaging (quick-frozen dumplings, ice cream, etc.), effectively reduce the brittle cracking of packaging materials under freezing conditions, and improve the heat sealing strength under low temperature conditions.
Adhesive solutions of Sinograce Chemical
Aiming at the above application structure of water-based adhesive, Anhui Sinograce Chemical Co., Ltd. has developed the single-component water-based adhesive 160 series and high-performance two-component water-based adhesive 170 series products, which can provide our customers with a variety of bonding solutions.
At present, our company's single and double component waterborne adhesive has been introduced to the market, the market feedback is good, the performance is excellent, fully able to meet the customer's composite needs of various packaging structures.
