CHARACTERISTICS AND EXAMPLES |
|
PP#5
(high strength)
Most woven bags or tarp
|
|
|
OPP#5 (oriented PP)
(unpigmented plastic films have high clarity, fairly
stiff, crinkles to touch)
- Garment bags
- Textile packaging
- Cigarette overwrap
- Potato chip bags
Note: These plastic films are difficult to discern
from PE films, except by texture and burn testing.
|
|
Co-extruded Polyethylene Film (LDPE/HDPE)#7
(high strength from HDPE, smooth, flexible surface with high printability from LDPE; woven texture is apparent,
but surface is smooth; often different color on opposite sides)
- Woven lumber wraps
- Mailing pouches and bank bags
|
|
|
Cross-linked PE#7
(no stretch, high strength, difficult to tear, crinkles
to the touch, yellowish hue when crumpled)
- Industrial film applications
Note: Cross-linked polyethylene plastic films are
films that have been altered on a molecular level in
order to significantly improve strength. Cross-linked
plastic films cannot be re-melted and therefore are
not usually recycled.
|
|
PVC#3
(Dissolves when touched with solvent based glues)
- Food contact packaging (especially frozen foods
due to its low oxygen permeability and cold temperature
performance)
- Food wrap or cling wrap
|
|
|
Nylon#7
(typically thick, high strength plastic films)
- Food contact packaging (e.g., soup pouches or seafood packaging)
Note: Most plastic films with food contact are not recycled due to residue.
|
|
PS#6
(crinkles to touch)
- Carrier sheets or other manufacturing materials
Note: Since they are crisper (less flexible) than
most other plastic films they may be classified as rigid
sheet rather than plastic films.
