Glossary

ADH Adhesive – An adherent used in a liquid or semi-liquid state, which forms an interface between two materials that hold the surface together with a strength adequate for the end use.
Cello Cellophane – Transparent film made from regenerated cellulose. Ranges in thickness, may be plain or barrier coated.
COF Coefficient of Friction – The ratio of the force that maintains contact between two surfaces and the frictional force that resists the motion of the surfaces.

  • Static Friction – between non-moving surfaces
  • Kinetic Friction – between moving surfaces
EVOH Ethylene Vinyl Alcohol – A copolymer of ethylene and vinyl alcohol with excellent oxygen barrier properties.
HDPE High Density Polyethylene
HIPS High Impact Polystyrene
Injection Molding A manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity.
MET OPP Metalized Oriented Polypropylene Film
NYL Nylon – Is a generic designation for a family of synthetic polymers known generically as polyamides.
OD Outside Diameter
OPP Film made from Polypropylene. Oriented in both machine and cross machine directions and heat stabilized.
OTR Oxygen Transmission Rate – The rate of passage of oxygen through the packaging film or laminate.
PAP Paper – The names of all kinds of matted or felted sheets of fiber. The thickness may vary depending on the end use.
PE Polyethylene – A synthetic thermoplastic material of high molecular weight resulting from polymerization of the ethylene gas under pressure and heat, plus catalysts.
PET Polyethylene Terephthalate – A thermoplastic polymer resin of the polyester family and is used in synthetic fibers; beverage, food and other liquid containers; thermoforming applications.
POS Point of sale.
PP Polypropylene – A synthetic thermoplastic material of high molecular weight resulting from polymerization of propylene gas under pressure and heat, plus catalysts.
Retortable Method of heat sterilization which renders a food product free of pathogens, making it shelf stable.
