Product Advantage
Delivers an immediate, aggressive bite into plastic film within seconds, ensuring 100% destructive fiber tear to permanently prevent unauthorized parcel opening.
Engineered with hyper-flexible chemical polarities to wet, flow, and bond instantly onto low-surface-energy recycled films as smoothly as onto premium virgin PE substrates.
Features an optimized low fluid viscosity profile (2,700 cps @ 160℃), ensuring continuous high-speed automation line coating without nozzle stringing or adhesive tailing.
Exhibits powerful tear resistance across a broad temperature span (-3℃ to 30℃), guaranteeing mailer seals will not turn brittle in winter or fail in summer.
Formulated with high-grade anti-oxidation stabilizers to prevent skinning, discoloration, or viscosity breakdown during prolonged heating in the melting tank.
Fully passed strict SGS environmental testing, aligning perfectly with global export standards including international REACH and RoHS chemical directives.

Perfect for coating the lip sealing release zones on protective padded bubble bags, document envelopes, and express heavy-duty cargo sacks.
FAQ
1. Q: What does "high tear strength resistance" or "destructive bond" mean?
A: It means that once the mailer flap is pressed closed, the adhesive bond becomes stronger than the plastic film itself. Any attempt to reopen the bag will result in the immediate shredding and tearing of the PE film, providing visible anti-theft proof.
2. Q: Can this hot melt glue handle bags made entirely from low-cost recycled plastic?
A: Yes, absolutely. Recycled plastics often contain trace impurities and wax layers that reject standard glues. This model features a high wetting formulation that cuts through surface contaminants to anchor deeply into the polymer.
3. Q: Why is a lower viscosity profile (2,700 cps @ 160℃) beneficial for mailer production?
A: High-speed bag-making machine require adhesives to apply fast and cleanly. The low viscosity profile allows automated slot dies to operate at peak speeds without causing messy trailing edge stringing or machine downtime.
4. Q: What clean-up protocol is recommended when cleaning the slot coating system?
A: To avoid altering the precise thermodynamic properties, flush the melter system with clean mineral oil at 120℃, then thoroughly purge the delivery lines with this same adhesive below 160℃ before starting production.
5. Q: Is this express bag adhesive safe for importing into countries with strict green regulations?
A: Yes, 100%. Our adhesive is completely non-toxic, low-odor, and thoroughly certified by SGS to fully satisfy international REACH and RoHS chemical safety mandates required for European and North American customs clearance.
