Deciding on Packaging Films

  1. 1. Your Packaging Matters People! Deciding on Packaging Films
  2. 2. Deciding on the best flexible plastic film for your packaging application can be a complicated process. There are many variables to consider in order to best display and preserve your packaged product. Established in 1968 Pyramid Packaging is a value-added, and ISO 9001 compliant supplier of packaging films.
  3. 3. Pyramid Packaging can help you select which of the following types of films & variables are required for your packaging application.
  4. 4. Anti-Static For static sensitive applications – like packaging for electronic parts or for static sensitive automated packaging or mailing equipment – anti-static additives lower surface resistivity and static decay times. Anti-Block Blocking is the term used to describe what happens when polyethylene film sticks together. Anti-block is an additive that roughens the surface of film at a microscopic level. This makes it easier for layers of film to separate. Anti-block makes bags easier to open.
  5. 5. High Density Polyethylene The chemical structure of high density polyethylene (HDPE) lends itself to greater toughness – roughly twice the tear and puncture strength and better chemical resistance than low density polyethylene (LDPE) and linear low density polyethylene (LLDPE). On the downside, HDPE film is less flexible and less clear than its LDPE and LLDPE cousins. courtesy of LADDAWN
  6. 6. Low Density Polyethylene Low density polyethylene (LDPE) is a popular choice for a wide range of light-weight packaging needs. LDPE provides moderate strength and good clarity for general purpose applications. A commonly used type of LDPE is actually called Clarity. courtesy of LADDAWN
  7. 7. Octene Octene is the strongest linear low density polyethylene (LLDPE). For a few pennies more per pound, Octene delivers the highest tear and puncture strength of any LLDPE material. Hexene Hexene is a very strong linear low density polyethylene (LLDPE) that stands up to more rigorous demands. Hexene is the most common choice where added strength is important. courtesy of LADDAWN
  8. 8. courtesy of LADDAWN Non-Scratch There’s really only one component in most low or linear low density polyethylene bags, film or tubing formulations that can be at all scratchy: anti-block. Anti-block additives work by making the surface of the film rougher. Non-scratch bags, film and tubing contain no anti-block additives and therefor provide smoother film surfaces.
  9. 9. Polypropylene Polypropylene (PP) is the choice when clarity is paramount. Polypropylene offers about five times the clarity (one-fifth the haze values) of Clarity low density polyethylene. Polypropylene is a common choice when packaging for display. courtesy of LADDAWN
  10. 10. Postal Approved These items are formulated to comply with the USPS T-3204 protocol for use on automation rate flat-size mail pieces. Performance standards met include haze, blocking, coefficient of friction and static charge decay. courtesy of LADDAWN
  11. 11. High Slip Some users require increases in slip additive to increase the degree to which their bags, film or tubing glide in a handling or packaging process. Low Slip Some users require low slip bags, film or tubing to decrease the likelihood of their product sliding when packaged. Mattress bags are a good example. Low slip bags are formulated with no slip additive. Slip Slip additives decrease the coefficient of friction (increase the slipperiness) of the surface of a bag, film or tubing. Standard formulations have enough slip additive. courtesy of LADDAWN
  12. 12. courtesy of LADDAWN Direct sunlight (UV light) causes unprotected film to discolor or become brittle. UVI/UVA (ultraviolet light inhibitor / ultraviolet light absorber) protects both the film and its contents from the damaging effects of the sun and inhibits thermal degradation of the film. Do not use UVI/UVA additive for film that may come in contact with agricultural chemicals or pesticides as they may reduce the product’s efficiency. UVI/UVA
  13. 13. courtesy of LADDAWN Packaged metal items can corrode during storage or shipment if exposed to oxygen, water and other contaminants. A Vapor Corrosion Inhibitor (VCI) is a film additive that has enough vapor pressure under normal circumstances to become a gas. VCI fills the interior of a sealed bag with molecules that adsorb onto the surface of a metal item to form a microscopic, protective barrier. VCI
