5.1.1 Plastic containers

5.1.1.1 what is type of plastic containers?

Originally, plastics were made from coal tar, but this has been superseded by oil.
There are two distinct classes of plastics used in packaging thermosets and thermoplastics.
Thermoplastic soften only once (during heating in the molding process) and are then irreversibly hardened (cured) while the latter have the property of softening repeatedly on heating and hardening again when cooled. Commonly used thermoplastic polymers and their abbreviations are listed in Table 6.4. The principal thermoplastic polymers used in packaging are the polyolefins (LDPE, HDPE, LLDPE and PP) ; PVC and PS.
Thermosets (phenol/formaldehyde and urea/formaldehyde are typical) are used for such purposes as making screw caps and glass and metal containers, while epoxy thermosets are used for lacquers in metal cans collapsible metal tubes.
Other plastics also used in more limited quantities and in special applications for pharmaceutical purposes include polyethylene teraphthalate (PET) and polycarbonate (PC), Polyvinylidene (PVDC) and Surlyn are used as coatings to provide heat-seal qualities and improve the barrier characteristics of films and laminates
