The Treofan Group is a manufacturer of biaxial oriented polypropylene film (BOPP) and cast polypropylene film under the brand name Treofan. The company also manufactures PLA film under the brand name Biophan. 

Note that Sample 3 had a 70 pm LLDPE layer between the acetic acid and the laminating adhesive. Sample 4 had a 20 pm layer of cast polypropylene between the simulant and adhesive. Both Samples 3 and 4 were provided to Rapra on a roll, which was stored at ambient temperature in the laboratory prior to removal of material for testing. 

Cast polypropylene (PP) is extensible, moisture-resistant, clear and seals at temperatures above those used in steam sterilisation. Oriented PP is strong and can be used in thin gauges. Unless coated or coextruded the film cannot be heat sealed without distortion. OPP is very clear, but can also make an opalescent film. Has a similar degree of inertness to HDPE. 

The objective of this chapter is to study the absorption and reflection of infrared light by the uncoated and A1 coated surfaces of polymier films using transmission and reflection techniques. For this purpose two commercial biaxially oriented polypropylene film, a cast polypropylene film, a milk cover and a chocolate coating material with their one surface coated with a thin aluminum layer were examined by irrfrared spectroscopy. One surface of the each film was coated with a thin aluminum layer.

The total thickness of the pouch and individual thickness of the different layers of all the retort pouches are presented in the Table 2. It has been observed that there is not much variation of thickness of pouches of individual layers from one laminate to another. The thickness of different pouches ranged from 135-110 pm for the opaque retort pouches and 150-120 pm for the clear pouches. Both imported and indigenous pouches were having uniform thickness throughout the same specimen. The OP-B pouch was having one extra nylon layer apart from polyester, aluminum foil, and cast polypropylene layer. In case of clear pouches, CP-C had only two layers that is polyester and CPP, whereas in CP-A, there were three layers, where the outer polyester layer was coated with aluminum oxide and nylon was also present. In the case of CP-B, the polyester layer was quoted with silicon dioxide. The thickness of the pouch had a direct influence on the heat penetration characteristics and product quality. Non uniform thickness can affect the machine performance, product protection, and integrity of the packages (Hemavathi, Anupama, Vani, Asha, Vijayalakshmi, Kumar, 2002). The...
