Sealing Machines
Sealing machines ensure that packages are airtight and tamper-proof. Heat sealers use heat and pressure to fuse packaging materials together, while induction sealers create a hermetic seal on containers using electromagnetic induction.
Labeling Machines
Labeling machines apply labels to containers, providing product information, branding, and regulatory compliance details. Pressure-sensitive labelers apply labels to flat or curved surfaces, while shrink sleeve labelers use heat to shrink labels tightly around containers.
Form-Fill-Seal Machines
Form-Fill-Seal machines combine multiple packaging steps into a single, automated process. Vertical FFS machines form bags or pouches from a roll of film, fill them with product, and then seal them. Horizontal FFS machines perform similar functions for products packaged in trays or containers. Cartoning and case packing machines package individual products into cartons or cases for efficient storage and transport.
Inspection and Quality Control Machines
Ensuring the safety and quality of food products is paramount. Food industry machines dedicated to inspection and quality control play a critical role in identifying and removing contaminants, defects, or inconsistencies.
