Food packaging
DIC manufactures multilayer films for use in packaging for breads, dessert cups and snacks.
Packaging for breads, dessert cups and snacks
Have you ever tried to open a bag of sweets on a picnic or when you wanted a snack only to find it just won't open? Have you ever pulled such a bag open with all your strength only to have the contents fly out everywhere? Or been reduced to tearing the bag open with your teeth? DIC's careful attention means that packaging made with DIC multilayer films open cleanly without the use of excessive force. These films facilitate the production of bread packaging, gelatin dessert cups and other products that even children and the elderly can open easily.
The benefits of ultrathin (less than 1 mm) films
DIC's easy-peel films for packaging comprise three or more layers. When a package made using these films is opened, only the adhesive (seal) layer releases easily. Because the films have multiple layers, a single film can deliver heat resistance, moisture resistance, impact resistance, transparency, protection from light, oxygen barrier and aroma retention, among others.
What would happen if these films were single-layer? A strong single-layer film used to securely wrap tofu and pickles would prevent the contents from leaking out, but you would not be able to peel off the film. If a weaker film was used, liquid would leak out before you got it home from the store.
DIC's multilayer films are manufactured using coextrusion, a method whereby the multiple resins used to make the film are extruded and laminated together simultaneously. In 1980, DIC became the first company in Japan to develop an easy-peel coextruded multilayer film. Since then, DIC has worked to improve the performance of its multilayer films. Extremely thin, multilayer films range between 20 and 50 μm. Once sealed, such films can maintain stable quality against heat across a broad range of temperatures.
Trusted films, 90% of which are used for food packaging
In addition to food packaging, multilayer films are used in packaging for components and cosmetics, among others. Nonetheless, approximately 90% of DIC's multilayer films are used for food. This is because DIC manufactures films that are particularly suited to the needs of food manufacturers, who put the utmost emphasis on quality. DIC continues to conduct research aimed at helping it find new ways to meet the needs of consumers who demand easy access to tasty food.
Recently, frosted glass and other types of matte packaging have grown in popularity for use with foods for which a sophisticated appearance is also important. In 2010, DIC developed a matte film with characteristics that include the texture of Japanese paper and a unique feel. These films can be imprinted with designs, eliminating the need for lamination of paper and film. DIC continues to work to enhance the performance of its multilayer films, as well as to reduce film weight and minimize use of resources.
