Flexible Films

POLYETHYLENE

  • Excellent moisture barrier characteristics.
  • Good clarity.
  • High gloss.
  • Good tensile strength.
  1. LDPE and LLDPE (Low Density Polyethylene and Linear Low Density Polyethylene)
    • Good clarity.
    • Good moisture barriers and fair-gas barriers.
    • Heat-seal option.
    • Strong and highly flexible.
    • LDPE is often selected for its high clarity, ease of processing and high gloss.
    • LLDPE is selected for its tensile and impact strength as well as its heat sealability.
    • Common Applications include; Bakery, fresh and frozen food, candy, retail rack display, industrial protection and more.
  2. High-Density Polyethylene
    • Found in many of the same applications as LDPE and LLDPE.
    • Down-gauging properties create an economic solution to other polyethylene film types.
    • Stiffer than other PE films and better for maintaining shape.
    • Strong and puncture resistance.
    • Good moisture-barrier properties.
    • Resistance to grease and oils.
    • Less tear-resistance than other PE films.
    • Common applications; cereal and cake mix bags, bakery, shipping sacks and more.

Polypropylene

  • Excellent moisture barrier characteristics.
  • Good clarity.
  • High gloss.
  • Good tensile strength.
  • High-melting point; ideal for packaging requiring sterilization at high temperatures.
  • Average gas-barrier properties.
  • Common applications; Candy, snack foods, bakery products, cheese, clean room and other sanitary items applications.

boPP (Biaxially Oriented Polypropylene)

  • Polypropylene film is extruded and stretched both in and across the machine direction.
  • Improved stiffness.
  • High tensile strength.
  • Excellent optics.
  • Good water-vapor barrier properties.
  • Can be monolayer or co-extruded structures, and transparent, opaque, or metallized.
  • Can be treated with specialty coatings for better sealability and barrier properties.
  • Common applications, commonly used in multilayer barrier films for snacks, pasta and confectionary goods.

PET (Polyethylene Terephthalate)

  • Good mechanical properties including toughness and stiffness.
  • Good thermal properties withstand higher-processing temperatures.
  • Polyester product.
  • Clear or pigmented options.
  • Common applications; used in multilayer barrier films.

boPET (Biaxially Oriented Polyethylene Terephthalate)

  • Polyester film made from stretched PET.
  • High-tensile strength.
  • Excellent heat resistance.
  • Good for microwave or oven use.
  • Chemical and dimensional stability.
  • High clarity.
  • High gas and aroma barrier properties.
  • Good electrical insulation.
  • Common applications:
  • White boPET used as lidding for dairy goods like yogurt.
  • Clear boPET used as lidding for fresh or frozen-ready meals.
  • Can be metalized for food production to protect against oxidation and for shelf-life expansion.
  • Microwave and oven cooking applications.

Nylon

  • Relatively high-melting point.
  • Good oxygen barrier properties – keeps out oxygen.
  • Good off-gassing properties – allows carbon dioxide and other gases to escape.
  • Easy to process.
  • Common applications; typically used in multilayer barrier films for cheese and microwave-cooking application.
