Hot melt glue Application Video of box sealing

Food and beverage packaging manufacturers face a dual challenge: the adhesive must deliver strong bonds on increasingly diverse carton substrates—plain corrugated, coated, and laminated—while simultaneously meeting strict food safety and environmental regulations. TONGDE 8078 is a food safe hot melt adhesive that resolves both challenges, delivering reliable bonding performance on the full range of packaging substrates while meeting GB 9685 food contact standards and REACH compliance requirements.

Food Safety Compliance: Non-Negotiable

In food packaging, every component that contacts or may contact the product must meet regulatory standards. Adhesive is no exception. While hot melt adhesives typically do not directly touch food, migration through the packaging substrate is a recognized concern—particularly on thin-walled cartons and folding boxes where the adhesive is applied close to the interior surface.

TONGDE 8078 meets GB 9685 (National Food Safety Standard for Use of Additives in Food Contact Materials and Articles), ensuring that all components in the formulation are approved for food contact applications. This compliance has been verified through independent testing and documentation, providing packaging manufacturers with the regulatory assurance needed for food industry supply chains.

Additionally, the product meets REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) requirements, making it suitable for export to European markets where REACH compliance is mandatory for all chemical substances manufactured or imported above one ton per year.

Bonding Versatility for Food Packaging

Food packaging spans a wide range of carton types, from simple brown corrugated shipping cases for bulk ingredients to premium coated and laminated retail boxes for consumer products. TONGDE 8078 is formulated as a food packaging box sealing adhesive that handles this diversity:

• Corrugated shipping cases: Strong initial tack and fiber-tear bonds on kraft and test liner
• Coated folding cartons: Reliable adhesion to clay-coated and PE-coated board used in cereal, snack, and frozen food packaging
• Laminated retail boxes: Effective bonding to BOPP and matte film laminates common in confectionery, tea, and premium food packaging
• Printed cartons: No ink bleeding or discoloration on offset and flexographic printed surfaces

Technical Performance

The moderate application temperature of 150–170°C is particularly beneficial for food packaging applications. Lower tank temperatures reduce energy consumption and fume generation, creating a cleaner production environment—important in facilities that also handle food products or operate under hygiene certifications.

The Hardness Advantage

The 70±5A Shore A hardness of TONGDE 8078 provides an important performance benefit for food cartons. Softer hot melts can allow carton flaps to gradually spring open under internal product pressure—a particular concern for bulging food packages like snack bags or cereal boxes. The firmer cured bond of 8078 resists this springback, maintaining carton integrity throughout the distribution chain.

Compliance Documentation
