Packages

Corrugated cardboard or paperboard, which is layered and folded to create the appropriate structure, is frequently used to manufacture paper cartons and boxes. Typically, specialised adhesives made for paper-based applications are used in the assembling of these packaging materials. These adhesives are designed to establish solid bindings and satisfy certain needs like quick cure times, flexibility, and compatibility for food packaging.

Water-based or solvent-based adhesives are frequently used to seal paper cartons and boxes. These adhesives are made to firmly attach the paper or cardboard layers to one another, giving the packaging structural rigidity while enabling simple recycling or composting of the components.

To improve the performance and utility of certain forms of paper packaging, resin-based polymers may occasionally be employed as coatings or laminates. Here are a few illustrations:

Barrier Coatings

Paper packaging can occasionally be coated with resin-based barrier coatings to increase its resistance to moisture, grease, and other liquids. These coatings can shield the package’s contents and stop moisture leakage or absorption. They are frequently employed in situations where a moisture or grease barrier is necessary, such as paper cups, takeaway containers and food packaging.

Laminates

Paper packaging’s strength, durability, and barrier qualities are improved by resin-based laminates. To increase the structural integrity of the packaging and to provide moisture resistance, a thin layer of resin-based material, such as polyethylene (PE) or polypropylene (PP), may be coated or laminated on top of paperboard or corrugated board.

Sealants

Heat-sealed closures are occasionally made with resin-based sealants and applied to paper packaging. The contents of the package will be kept safe thanks to the secure and tamper-evident seal provided by these sealants. They are frequently utilised in products including pouches, sachets, and bags.

It’s crucial to remember that the particular resin materials used in these applications might vary and are normally selected depending on the individual packaging requirements, regulatory concerns, and compatibility with the packaging materials.
