Product Advantage
Specifically engineered for frozen environments, this adhesive features a lowest application temperature down to -20℃. It allows labels to be applied directly in unheated cold-storage warehouses without losing its instant grab.
Once applied, the adhesive matrix remains highly flexible and robust across a versatile service temperature range from -40℃ to 40℃. It prevents the glue line from becoming brittle or delaminating in deep-freeze tunnels.
Boasting a high peeling value and premium initial tack, this hot melt PSA forms an immediate, permanent bond upon contact. It ensures tight label closure, completely eliminating edge flagging on curved or irregular packaging.
This versatile adhesive formula exhibits strong thermodynamic wetting, enabling it to bond securely to various materials, including corrugated cardboard, low-density polyethylene (LDPE) films, glossy plastics, and frozen vacuum pouches.
Formulated with high-grade synthetic elastomers and stabilizers, the product provides outstanding aging resistance. It maintains its precise viscosity, color stability, and cohesive strength over extended storage periods without degradation.
Prioritizing global market entry requirements and consumer safety, our cold-chain adhesive fully complies with REACH and RoHS standards, making it safe for food packaging labeling and pharmaceutical cold-chain tracks.

Product Uses
Deep-Frozen Food Packaging Labeling
The primary application is coating label stocks for frozen meat, poultry, seafood vacuum pouches, ice cream containers, and pre-packed frozen meals that undergo blast freezing.
Pharmaceutical Cold-Chain Tracking
Perfectly suited for labeling blood bags, plasma containers, medical culture vials, and vaccine boxes requiring strict cryogenic storage down to -40℃.
Cold-Storage Logistics & Inventory Barcodes
Widely used for distribution shipping labels and barcode tracking stickers applied directly to corrugated boxes and stretch wraps inside refrigerated warehouses and reefer containers.
FAQ
1. Q: Can this label adhesive be applied directly onto pre-frozen surfaces?
A: Yes. This premium formulation supports a lowest application temperature of -20℃, meaning it can flow and grab onto cold surfaces where standard label adhesives would instantly freeze and fail.
2. Q: What is the recommended clean-up procedure for the slot coating heads?
A: We recommend consulting your equipment manufacturer, or flushing the melter system with clean mineral oil at 120℃, followed by thoroughly rinsing with the same adhesive model below 170℃.
3. Q: Does this freezer-grade glue comply with international food packaging standards?
A: Yes, it is fully compliant with REACH and RoHS environmental safety standards, ensuring it contains no restricted harmful chemicals and is perfectly suitable for secondary food labeling.
4. Q: Why is the running temperature (170℃ - 190℃) higher than standard hot melts?
A: The formulation utilizes specialized high-cohesion polymers to maintain sub-zero elasticity. The higher operating temperature ensures optimal melt flow and a uniform coating thickness during high-speed slot tooling.
5. Q: What processing precautions should our production operators follow?
A: Do not mix this product with any other types of adhesives to avoid property alterations. Keep the container sealed tightly to avoid contamination, rotate your stock using the First-In, First-Out (FIFO) rule, and always wear thermal protective equipment.
