Two new investments by Sonoco Products (Malaysia) Sdn Bhd will increase the local composite cans industry. The company plans to invest $20 million in the development of a high-speed manufacturing line in Kajang, Selangor, to manufacture snacks and other packaging items. Another $5 million will go toward establishing a Sonoco Innovative Packaging Solutions Studio. The company will install three high-speed composite can lines and two metal end presses at its flexible packaging plant in Kajang, Selangor.
The production process varies by type of composite can. Spiral wound cans are produced by winding diagonally four layers of material, with the bottom layer made of tin and the middle layers of paperboard. The outermost layer can be omitted, depending on customer preference, but it increases the production cost. Linear draw cans are made by drawing the materials together through glue or tooling. The finished can is cut apart to make a single unit.
Other types of composite cans include spiral wound and linear draw. Spiral wound cans are produced by winding four layers of material, including the bottom tin layer and the middle two layers of paper board. The fourth layer is optional and depends on customer preference, but adds to the production cost. Linear draw cans are produced by drawing the materials through a tooling process and are available in a range of sizes.
Composite cans are typically produced using a combination of different materials. The material used for making these cans is called a retort pouch. Its laminated cellophane and aluminium foil create an sterile environment for processing and packaging. The materials are used to maintain product safety and hygiene. These pouches are made with high-quality materials. The material used is based on end user preferences.
The market for composite cans is growing steadily. The company expects to install its first can production line in the third quarter of 2014 and to operate metal end presses and an extrusion laminator at the plant. In addition, the composite cans manufacturer will also produce components for composite cans and will invest $5 million in an IPS Studio. In 2014, the company is expected to add six new lines to its plant.
The composite cans market is divided into two main types: linear draw and spiral wound. Spiral wound cans are made by diagonally winding four layers of material – a bottom layer of tin, three inner layers of paper board, and an outer layer of acetate. Both of these types of composite cans are made of high-quality materials and are suitable for food and beverage applications. The manufacturing process for these two types of cans is very efficient.
