Packaging

Delivering the right wrapping

One of the most important factors affecting the consumer’s decision to purchase a product is attractive presentation. 
In addition to its esthetic aspect, packaging today can also be given important functional properties. State-of-the-art additives help to protect both the packaging and its contents. The use of antioxidants in plastic food packaging, for example, can allow a reduction in the use of conservation agents in the contents.

Plastics combine appeal with function

The most common material used in packaging today, plastic can meet a variety of needs thanks to its versatility. Plastic can be rigid or flexible, transparent or opaque, and it can be molded into a wide variety of shapes and sizes. 

In the home, plastic bottles and secure lids help to ensure safety. In the food and beverages sector, plastic packaging helps preserve freshness and flavor. It is tough enough to withstand transportation and helps to minimize fuel consumption on account of its light weight. Plastics require less energy to manufacture than other materials and keep out dirt because they are densely constructed. All these properties make plastic packaging suitable for office equipment, computer components and other delicate products in addition to food and beverages. Some types of plastic are recyclable and can be turned into products such as building materials, flooring, hoses, floor tiles and mats.     

A variety of different plastics lend themselves to packaging, depending on the application. Polyethylene terephthalate (PET), which is the most recycled material, polyethylene (PE) and polypropylene (PP) are commonly used for bottles, trays and as thin flexible film, for example. Trays can also be made of polystyrene (PS), which is suitable for cups and other heat-resistant recipients as well. Polyvinyl chloride (PVC), which is flexible, light, cost effective, transparent, and tough, has excellent organoleptic, oxygen and water barrier properties, meets requirements for cling film and blister packaging for batteries, electronic items, tools and toys as well as for food. Polyamide (PA) provides flexible film with barrier properties. Polyurethane (PU) packaging foam, which can be custom-produced to keep items safely in place during transportation, is widely used for electronic equipment and other delicate items as well as for large industrial components.

To make them suitable for packaging applications, plastics require stabilization as they are not inherently resistant to light. 

SONGWON develops, manufactures and supplies additives that stabilize plastics as well as adhesive solutions for labeling, helping to enhance the appearance and functional properties of the wide variety of packaging available today.
