    Description
  • Bi-Axially Oriented Polypropylene Film (BOPP)

    BOPP Film is a bi-axially oriented polypropylene (BOPP). This material has good clarity, resistance to UV light, excellent chemical and abrasion resistance, and a smooth surface. The clear material has a reasonable scuff resistance and a great acid resistance. Our material is also inert to most mild chemicals and has a fair heat resistant allowing for heat sealable BOPP films. This material is softer and more flexible than polyester.

    We have the BOPP film for you, no matter what your application. There are over 1,000 variants of BOPP films. Our films include many types of coatings, such as silicone, adhesive, pre-mask, corona, print treatments, clear or matte etc. BOPP film has a wide range of applications including but not limited to products for the metallizing, packaging, stationery, tape and label, as well as decorative markets.

    Here is a small list of some of the different types of BOPP Film Supply we we carry, laminated BOPP film, industrial BOPP film, metallized BOPP film, co-extruded BOPP film, tape BOPP film, label BOPP film, packaging BOPP film, stationery BOPP film, and decorative BOPP film. "Biaxially Oriented" tell you that the polypropylene film has been stretched in both the machine direction (MD) and across machine direction (AMD). Superior strength at low gauges (allows for high speed processing), flatness, clarity and printability, are just a few of the reasons BOPP film has become the most rapidly implemented film product across the world.

    The table below lists only a few grades we have available so be sure to contact a representative today so they can tailor a BOPP film product to suit your particular need. The BOPP market continues to grow. Newer solutions help us create more demanding films, that have become lighter, stronger, and better suited for printing. With continued research and development, BOPP has potential to replace everyday wood based paper with synthetic paper.

    Also you may find our handy BOPP Conversion Table useful, and OPP Film and Polypropylene Film - PP Film helpful.

  • High-Density Polyethylene Film (HDPE)

    With a low coefficient of friction, High-Density Polyethylene Film (HDPE) is prized for its slip resistance and release properties, as well as its excellent impact, tensile and compression strength. Dense and unbranched, this material does not splinter, corrode or abrade easily and is stress-crack resistant.

    Slip-resistant
    Strong
    Food-safe

    HDPE film does not retain harmful bacteria, is extremely resistant to various cleaning agents and can be sterilized in boiling water. Food-safe, moisture, stain and odor resistant, and printable in various forms, HDPE plays an important role in most industries. Its clarity makes for appealing food packaging, while its slip resistance is valuable in textile packaging.

    This material is available clear or opaque in a variety of colors, and can be customized in size, shape, and density to suit your needs.

    We also have MDPE Film and LDPE Film.

  • Low Density Polyethylene Film (LDPE)

    Soft, tough and flexible, Low Density Polyethylene film is favored for its resilience against a majority of chemicals and organic solvents. When LDPE film is incorporated into a packaging laminate, it offers excellent seal strength to package the most demanding products. Its low conductivity makes it useful in low temperature electrical applications, while its durability and excellent process-ability make it the all-purpose film to turn towards.

    Superior Flexibility
    Excellent Process-ability
    Optimum Tear Strength

    LDPE film is polymerized using a free radical that produces a large amount of short and long chains, limiting its ability to form high levels of crystallization. The low level of crystallinity attributes to the flexibility, clarity and elongation. The simple repeating polymer unit is very inert, leaving the film resistant to many chemicals. While LDPE is very popular as the main resin for shrink film and sealing layers in packaging laminates, we customize our film to suit many purposes and can adjust everything including color, thickness, size, printability, release and finish.

    We also have MDPE Film and HDPE Film.

    Please contact a representative today so they can tailor a LDPE film product to suit your particular need.

  • Medium Density Polyethylene Film (MDPE)

    Our MDPE (Medium Density Polyethylene) is a plastic material with a good shock and drop resistance. This material is less notch sensitive than HDPE, and its stress cracking resistance is better as well. Our films include many types of coatings, such as silicone, adhesive, premask, corona, print treatments, etc. for labels, printing, and protective purposes. MDPE is defined by a density range of 0.926 - 0.940 g/cc. (Grams per Cubic Centimeter) We also have HDPE Film and LDPE Film.

    Please contact a representative today so they can tailor a MDPE film product to suit your particular need.

  • Oriented Polypropylene Film (OPP)

    OPP, Polypropylene, films are a material with unique strength, thinness, density confirmation transparency, and gloss. It also has excellent moisture proof properties which allows for clear printing using normal inks. This can be used in packaging food, textile products, pharmaceuticals, and miscellaneous goods. Our films include many types of coatings, such as silicone, adhesive, premask, corona, print treatments etc. for labels, printing, and flexible packaging purposes.

    Please contact a representative today so they can tailor a OPP film product to suit your particular need. Or find out more about Polypropylene Film - PP Films or BOPP Film.

  • Polyethylene Terephthalate Film (PET)

    Our PET (polyester) film has high temperature and excellent barrier properties. It is used as a substrate for laminating and extrusion coating. PET film is used in flexible packaging of products. PET exhibits outstanding dimensional and thermal stability and excellent tensile strength. However, these same properties also contribute to poor stress-flex resistance and the potential to pinhole.

    Polyethylene terephthalate, PET, is rarely used unsupported in the paper and film industry and is normally laminated to a polyolefin sealant web for heat seal-ability and improved stress-flex, pinhole, and dart-tear resistance. Our films include many types of coatings, such as silicone, adhesive, pre-mask, corona, print treatments, etc. for labels, printing, and protective purposes. Of course we also offer untreated super clear polyester film.

    Please contact a representative today so they can tailor a PET film product to suit your particular need.

  • Polyester Film

    Our polyester film contains properties such as high strength, easy machine-ability, dimensional stability, surface treat-ability, clarity, tear resistance, moisture resistance, etc. Polyester film is used in many types of packaging applications ranging from food and drugs to industrial and consumer goods. Vinyl coated polyester and other coatings make PET film a versatile product. Many refer to this material as Mylar. Mylar is the DuPont trademark for polyethylene terephtalate (polyester) film. Which is also referred to as PET film.

    As a plain, metallized polyester, or colored our nylon polyester film is formable, heat-shrinkable and/or coated for barrier, metal adhesion, laminating adhesion, extrusion coating adhesion, printing, or sealing. Polyester Urethane Laminate, PUL, offers greater toughness and is biodegradable by exposing to conditions of high humidity.

    The combination of physical, thermal and optical properties of Polyester Film and Plastic Sheet allow this film to be used in a variety of applications, in a wide range of industries. We can also produce Biaxially-oriented polyethylene terephthalate, BOPET. BOPET is suited more towards high demand applications, such as solar panel arrays, medical, and food packaging.

    Please contact a representative today so they can tailor a polyester film product to suit your particular need.

  • Polyethylene Film (PE)

    Polyethylene film, PE Film, is typically sold in rolls of various sizes and thickness. This highly conformable product bonds well to most surfaces over a wide range of temperatures. Polyethylene is the thermoplastic commodity most heavily used in consumer products worldwide. This product also comes in various density confirmations. Our films include many types of coatings, such as silicone, adhesive, premask, corona, print treatments, etc. for labels, printing, and protective purposes. HDPE Film, MDPE Film, and LDPE Film are variants each with their own distinctive properties.

    Please contact a representative today so they can tailor a Polyethylene film product to suit your particular need.

  • Polypropylene Film

    Our polypropylene film material is most often a clear or matte bi-axially oriented polypropylene or mono-axial oriented polypropylene. Polypropylene is a thermoplastic polymer from the monomer propylene, which has good clarity, resistance to UV light, excellent chemical and abrasion resistance, and a smooth surface. The clear material has a reasonable scuff resistance and a great acid resistance. Our material is also inert to most mild chemicals and has a fair heat resistance.

    Our polypropylene films are softer and more flexible than polyester. Our films include many types of coatings, such as silicone, adhesive, premask, corona, print treatments, etc. for labels, printing, and protective purposes. As with most of our materials we can also produce polypropylene to your specifications. Most polypropylene has a melting point of 320 degrees Fahrenheit. For more specific variants we also produce BOPP Film and OPP Film.
