other packaging polymers

Cellulosics

Cellophane, based on wood cellulose, a thermoset

Superior deadfold and machinability

Lower static gen, cost and performance disadvantage

Extruded to high clarity tubular shapes

Epoxies

Thermoset polymers based on epichlorohydrin and bisphenol-A (BPA bad)

Polycarbonates

Carbonic acid and BPA

HIGHEST IMPACT RESISTANCE

Clarity equal of glass (glass glazing)

Returnable large bottles and jugs

Acrylonitrile copolymers

Barex

Good oxygen and gas barrier properties

Poor vapor property

Resistance to aggressive solvents

PUR

Thermoset types cured by moisture

Adhesive and coating base resins

Foam in place

PEN

Used for hot fill and retort apps

Blocks UV light

High potential for glass replacement

Styrene butadiene

High clarity, tough, easily processed

Low surface hardness, low stiffness, low resistance to organic solvents, poor performance when exposed to UV

K-resins have high permeation rates

PCTFE (aclar)

HIGHEST MOISTURE BARRIER

Good barrier to other gases

Excellent optical properties, readily thermoformed

Blister packs for sensitive unit dose pharma tabs, tolerate cryogenic temps and ionizing radiation

Bioplastics

Developed renewable resources

Cellulose starches biopolymers

PLA

PLA

Stiff clear polymer

Could be mistaken as PS

Low heat distortion temps

Thermoset plastics

Phenol formaldehyde and urea formaldehyde for specialty closures

Superior solvent resistance, ideal for aggressive solvent xontact materials

Not prone to develop sink marks

Used in conjunction with fiber glass for highly durable shipping containers

Acrylonitrile butadiene styrene

Tough high impact resistant material
