Definition of Composite Paper

Composite paper is paper that is processed together with other packaging materials such as plastics and metals, which aims to improve the brittle force, stiffness and strength of the material. Paper mixed with metal and formed into a kind of cans called composite cans, used for citric juice, spice containers (spices), chocolate boxes, dry soups, chemicals and medicines. The packaging industry has made composite cans that can withstand vacuum and withstand temperatures of about 49 o C, so it can be used for preserving jam (jam). Tube carton is used for margarine and ice cream.

There are 3 (three) types of construction of composite paper cans, namely: spiral shape, sewn lobe ( lap seam ) and compound roll ( convolute ). The spiral shape consists of several layers of different materials with an overlapping connection angle. Body composite lobe in sewing, made of laminated material, while the type of composite roll consists of several layers of coils. The carton tube is a tube-shaped package of cardboard or paper.

The larger tube shape is called the carton drum. Tube cartons are widely used for packing chips, while drum cartons are used for powdered materials or dry products. For packing of liquid material then carton packing coated with plastic.

The advantages of composite tubes and cartons are light weight, easy to open and close, can be re-coated with other materials so impermeable. Usually made in the form of folding / cardboard folding folds made of duplex material and the like, the thickness of the duplex is adjusted to the weight of the product or the thickness as well as the main attraction. With the development of packaging technology, cardboard packaging has good moisture resistance and can be designed according to the nature of fresh fruit.

The technology is adopted from the packaging technology of seafood products. Packaging from local materials made of paper remains in good condition even though placed in a room with moisture up to 80% (Trubusid, 2008). Based on the dimensions of the grooves, flat cardboard sections, and the number of plots, corrugated cartons are divided into several types, namely (International Trade Center UNCTAD / WTO 1993) .:

  • · The carton is not flat
  • · One-faced carton,
  • · Single wall double wallboard,
  • Double wall double wallboard,
  • Three double-wall double-walled cartons
