Food Packaging Films 101

  1. 1. Your Packaging Matters People! Understanding Food Films
  2. 2. Not these kind of food films
  3. 3. We mean these kind of food films
  4. 4. Plastic film for food packaging offer several advantages over their rigid counterparts. . 1. lightweight 2. easy to print on 3. good barrier properties 4. recyclable & or reusable
  5. 5. Deciding on the best type of food packaging film can be confusing. Low Density Polyethylene – LDPE Linear Low Density Polyethylene – LLDPE High Density Polyethylene – HDPE Polypropylene-PP Cast Polypropylene: CPP Oriented Polypropylene: OPP Biaxial Oriented Polypropylene: BOPP Metallized Oriented Polypropylene: MET-OPP Polyethylene Terephthalate: PET Metallized Polyethylene Terephthalate: MET-PET Nylon Polyolefin
  6. 6. We can We can We create value by helping our customers select the best films for their food packaging needs.
  7. 7. Commonly Used Food Packaging Terms Barrier Level: a films ability to prevent moisture from penetrating the film itself Clarity: the measurement of a film’s transparency Converting: process of cutting a plastic film it into lengths, bond the edges, resulting in plastic bags Film Gauge: film thickness measured in mils Laminated Films: Lamination (bonding together) of two or more films that improves the appearance, barrier Properties Metallized: applying a thin coating of metal to a nonmetallic surface by chemical deposition or by exposing the surface to vaporized metal in a vacuum chamber Packaging Films: are melted plastic resin which are extruded into sheets or rolls Sealability: bonding process between two layers of film
  8. 8. LLDPE, LDPE Films Linear Low Density Polyethylene – Low Density Polyethylene Properties: •these films are inexpensive and have good clarity •they are often used used to package fresh, produce, frozen foods & baked goods
  9. 9. HDPE Films Properties: •HDPE film is found in many of the same applications as LDPE and LLDPE •it’s stiffer than other PE which makes it an ideal film that needs to hold its shape •since it has good moisture barrier properties, it is resistant to grease and oils •HDPE is often used inside a box to preserve its contents such as cereal bags or cake mixes High Density Polyethylene
  10. 10. PP Films Properties: •PP is soft, & clear glossy film with good moisture barriers & high oxygen transfer rates •often used as plastic food bags in bakeries, and food markets •PP films are less flexible than LDPE Polypropylene
  11. 11. CPP Films Cast Polypropylene Properties: •CPP films are used to package baked goods, confectionary items •they’re also used to make flexible & stand up pouches •they are easily printable & run efficiently on packaging equipment like baggers & VFFS
  12. 12. OPP / BOPP / MET BOPP Films Properties: •BOPP & OPP are the same types of film •film is stretched in both the machine and transverse directions after it’s extruded •this increases the film’s stiffness, clarity & tensile strength •because of the film’s stiffness its used as a wrap for hard candies and chocolates •resistant to heat and moisture •has a shiny high gloss appearance •when OPP/BOPP films are laminated with metal foil (MET) it will increase the film’s oxygen & water barrier & block out UV rays Orientated Polypropylene… Bi-Orientated Polypropylene...Metallized Bi-Orientated Polypropylene
  13. 13. PET / MET PET Films Polyethylene Terephthalate / Metallized PET Properties: •very good oxygen barrier •heat resistant •strong film with good durability •when PET films are laminated with metal foil it will increase the film’s oxygen- water barrier & block out UV rays •metallized films for flexible packaging are essential when the product requires extra protection to ensure a longer shelf life •MET PET provides protective properties for food items requiring restricted visibility.
  14. 14. Nylon Films Properties: •since Nylon films have a high melting point, they are used for cooking applications such as boiling, microwaves & baking •very good clarity & moisture barriers •considered a very strong film
  15. 15. Polyolefin Films Properties: •these films are also used for shrink wrapping applications & allow products to stand out when displayed
