Polymer composite film heat sealing equipment

1. Equipment classification and working principle
1. Classification by heat sealing method
Constant temperature heat sealer
Principle: Directly press the film material through the upper and lower heating plates, suitable for sealing of flat or simple shapes.
Features: Simple structure, low cost, suitable for small batch production.
Application: Food bags, aluminum-plastic blister packaging of medicines.
High frequency heat sealer
Principle: Use high-frequency electromagnetic field to make the internal molecules of the film material vibrate to generate heat, and achieve contactless sealing.
Features: Fast sealing speed, suitable for thick film or composite film containing aluminum foil.
Application: Medical infusion bags, waterproof breathable film.
2. Classification by degree of automation
Manual/semi-automatic equipment: Suitable for laboratory or small-scale production, flexible operation but low efficiency.
Fully automatic production line: Integrated feeding, heat sealing, cutting, detection and other functions, suitable for industrial production.
