| Classification | Meets standards | Physical and mechanical properties | Durability and aging performance | Chemical and safety indicators | Technological and Construction Performance |
| General purpose and high performance packaging adhesives | GB 18583 | Viscosity range: 500 – 5000 mPa·s (adjustable to suit coating) | Temperature resistance: -20°C to 121°C (can withstand boiling) | VOC content: < 50 g/L, compliant with the strictest environmental regulations. | Applicable processes: Roller coating (dry/wet lamination), blade coating |
| ASTM D1876 | Solid content: 40% – 55% | Media resistance: Excellent resistance to oils, greases, acids, and alkalis (passed relevant tests). | Odor: Extremely low, odorless, meets indoor and packaging requirements. | Opening hours: 5 – 20 minutes (adjustable) |
| FDA 21 CFR 175.105 | Peel strength: 4 – 12 N/cm (depending on model, up to 8-12 N/cm for film lamination) | Aging resistance: The composite packaging undergoes accelerated aging tests to simulate shelf life. | Toxic substances: Free from isocyanates, nonylphenol, and other harmful substances; RoHS/REACH compliant. | Curing conditions: 40-55°C drying room, 24-48 hours |
| Tg (glass transition temperature): -30°C to 0°C (usually lower to maintain flexibility) | | | Drying speed: Matches the drying tunnel temperature of the laminating machine (80 – 100°C) |
| Specialty functional adhesives | GB/T 2790 | Initial adhesion: Extremely high; almost impossible to shift after pressure is applied. | Excellent resistance to long-term damp heat aging; lifespan far exceeds that of ordinary water-based PU. | Environmental protection system: Water-based, non-toxic and non-flammable, safe for transportation and storage. | Opening hours: Very short (1-5 minutes) to standard (10-15 minutes) optional |
| GB/T 7124 | Final strength: Peel strength 5 – 9 N/cm | High and low temperature cycling performance: Stable performance within the specified temperature range according to the customized Tg. | VOCs: Extremely low, improving the working environment. | Pressing time: Short, allowing for immediate or rapid transition to the next process, improving efficiency. |
| Compliant with GB 18583 and RoHS/REACH | Tg range: -40°C to +40°C, customizable | Heat resistance: The upper limit of the operating temperature is 80°C. | | Applications: Suitable for both spraying and roller coating; adaptable to automated production lines. |
| Hydrolytic stability: Strength retention > 85% after 7 days at 70°C/95% RH. | | | |
| Special adhesive for difficult-to-bond materials | ASTM D3330 | Peel strength for PP/PE: ≥ 4 – 6 N/cm (cohesive failure) | Aging resistance: Maintains long-lasting adhesion to difficult-to-bond substrates and does not detach naturally. | Environmental friendliness: Water-based system, safe and non-toxic. | Surface treatment: For best results, it is strongly recommended to treat the substrate with corona, flame, or plasma. |
| Compliant with GB 18583, RoHS, and REACH. | Applicable substrates: Specifically designed for PP, PE, EVA, etc., and can be extended to some engineering plastics and painted surfaces. | Environmental tolerance: Able to withstand normal changes in ambient temperature and humidity. | Special Features: The formula contains a special adhesion promoter for difficult-to-bond materials. | Application methods: Spraying, brushing, roller coating |
| | | | Drying and curing: The process is similar to that of general-purpose water-based PU, but it is necessary to ensure that the adhesive makes full contact with the treated substrate surface. |
