Choose the Right Material for your Application

Converting Technology offers a wide selection of high quality flexible packaging materials for our Rollbag pre-opened bags-on-a-roll. These choices can help you create a package that can both showcase your products and protects them during shipment. Whether you desire high clarity or high opacity, breathability or high barrier, protection from static charges or corrosion, we can help you create solutions to your packaging problems.

The following is a brief description of the choices available.Polyethylene Film Extrusion

Specially-formulated linear low density polyethylene (LLDPE) blend is ideal for everyday packaging needs and is the most common film for our Rollbag pre-opened bags on a roll. This blend provides a higher strength at a lower gauge than traditional low density polyethylene (LDPE), allowing a thinner bag to be used. Our LLDPE blend resists punctures and tears while maintaining clarity and flexibility. It is available as clear, tinted, or opaque in color.

High density polyethylene (HDPE) blend is a unique film for moisture and vapor barrier applications, or for scratch-resistant requirements. HDPE is typically stronger than an LLDPE bag at the same gauge, however, significantly stiffer. HDPE tends to be slightly opaque in appearance (translucent) and is typically used for packaging medical devices and applications for moisture control is important

Coextruded (Coex) Polyethylene Blends. When a single resin type is not sufficient to solve all of your package requirements, many customers turn to coextrusions. By definition, a coextruded (coex) material is a combination of two or more resins into a multi-layer structure. For example, you can combine the moisture barrier of an HDPE resin with the puncture resistance and sealing properties of LLDPE.

Another common use is for combining multiple material colors into one layer of film, such as in Mail Fulfillment applications where the film is made with a white outside and gray inside for a package that protects the contents from visual identification.

Polypropylene. Looking for a material that will showcase your retail product? Polypropylene is an entirely different resin that provides significantly higher clarity and strength than polyethylene. It is also commonly used where a higher vapor and moisture barrier is desired in a high clarity film.

Nylon material offers the highest levels of puncture/tear resistance, and is an excellent oxygen (O2) and carbon-dioxide (CO2) barrier. Typically produced as a co-extruded material, it has exceptional strength and clarity, making it a top choice for vacuum-packaging applications such as cheese, meat, and other food products.

Biodegradable film is a polyethylene blend with a bio-additive for enhanced biodegradability. This material comes in clear or with a green tint. It complies with the following tests:

  • ASTM D5338-98–Aerobic biodegradation of plastic materials under controlled composting conditions (simulating composting)
  • ASTM D5511–Anaerobic biodegradation of plastic materials under high-solids anaerobic digestion conditions (simulating landfill)

Anti-static material comes in clear or color tinted (such as pink) varieties and is designed for static dissipative (SD) applications. Unlike regular LDPE/LLDPE/HDPE materials, our anti-static material will not produce static charges and therefore is ideal for use wherever bags may come in contact with sensitive electronic component

Volatile Corrosion Inhibitor (VCI) materials can effectively eliminate corrosion for metal products without the use of oils or other messy corrosion inhibitors. Formulas are available for ferrous metals (rust control) and non-ferrous metals, and the materials are commonly color tinted yellow, green, or blue to identify them as vapor corrosion inhibitor materials.

Embossed Film is formulated for anti-scratch purposes and is most common for packing polycarbonate lenses and other products that are easily scratched by traditional bag materials.

Polyester is another good choice for oxygen and moisture barrier applications. It is available in clear, opaque, and metallized configurations and is commonly used for applications such as Coffee, Nuts, and other food packaging

Ultra Violet Inhibitor (UVI) material extends the shelf life of your packaged product in sunlight conditions, by preventing the bag material from premature decomposition and failure. Combined with ultra-violet inhibitor fade-resistant printing inks, we can help you create a package that withstands the rigors of outdoor package storage.
