What are factors to keep in mind while choosing case and carton sealing?

Here are some key factors to consider when choosing case and carton sealing methods:

Application:

• Generic application: All standard case and carton packaging adhesives. 
• High heat resistance: When the packaging demands adhesives with high heat resistance.           
• Difficult to bond: When we need to bond difficult substrates, including varnish, coatings, or recycled papers.     
• Blast freezer: When the packaging demands adhesives with cold resistance to keep case and carton sealed during the storage of frozen food.  
• Low temperature: When customers want to improve the energy consumption and operator safety.

Product and Packaging:

• Product weight and fragility: When it comes to heavier or more delicate products, it requires strong seals and additional reinforcement for strength.
• Box size and material: Remember, sealing methods must be compatible with the box size and material to make sure that they have proper bonding and avoid damage.
• Stacking requirements: If boxes are piled during storage or transport, seals must be strong enough to resist the weight of other boxes.  In addition, consider palletizing adhesives for enhanced stability.

Volume and Speed:

• Production volume: Automated sealing solutions, such as case sealers, offer better speed and efficiency than manual sealing for high-volume operations.
• Desired sealing speed: You must consider the required sealing speed per hour to determine if manual or automated sealing is more convenient.
