Induction sealers use electromagnetic induction to create a hermetic seal on containers, often employed in the pharmaceutical or food industries. For instance, many snack food companies use heat sealers to maintain the crispness of their products. Yogurt producers employ sealing machines to ensure the integrity and freshness of individual containers.
Wrapping Applications
Wrapping machines enclose products in a protective layer of film or other material, offering both physical protection and enhanced presentation. Flow wrappers create a continuous sealed package around individual items, common for wrapping candy bars or snack cakes. Stretch wrappers secure products on pallets, while shrink wrappers use heat to conform film tightly around the product, enhancing stability and appearance. Wrapping machines are vital for ensuring the hygiene and presentation of various food products.
Labeling Solutions
Labeling machines apply adhesive labels to packages, providing essential product information, branding elements, and regulatory compliance details. Pressure-sensitive labelers are widely used for applying self-adhesive labels to various containers. Wrap-around labelers are designed to apply labels around cylindrical objects like bottles or cans. Sleeve labelers shrink sleeves onto containers for all-around branding and tamper evidence. A restaurant using their own brand of sauce would utilize labeling machines to efficiently brand their product. A cannery would also use labeling machines to label their canned food.
Case Packing Functions
Case packing machines automate the process of placing individual items into cases or cartons, streamlining packaging and preparing products for shipping. These machines improve efficiency and reduce labor costs. For example, packing lines for bottled beverages or canned goods often incorporate case packing machines to expedite the packaging process.
Form-Fill-Seal Integration
Form-fill-seal machines, often abbreviated as FFS, represent a fully integrated packaging solution. These machines form the package from a roll of material, fill it with product, and then seal it, all in one continuous operation. Vertical FFS machines, or VFFS, are commonly used for packaging snacks, powders, and granular products. Horizontal FFS machines, or HFFS, are suitable for packaging items like cookies, crackers, or other flat products. A company packaging potato chips would use a vertical form fill seal machine to form the bag, fill it, and seal it. Coffee bean and ground coffee companies would also utilize VFFS.
The second main category of food packing machines is based on the level of automation involved:
