Plastic Wrap Info

This is a list of the plastic wraps and their chemical/physical quantities about them:

• PVC Wrap: PVC is an acronym for polyvinyl chloride, its chemical name. Plastic wraps that are made of PVC are called PVC wraps. The films in PVC are used for catering purposes. These films are useful because they make for visual appeal by instantly clinging on to most surfaces of foods. Unfortunately, the films can compress to the food too much and stick to the food, making the food toxic. PVC wrap was the first wrap ever made in the world. (http://www.ehow.com/)
  

  

  
  

• PVdC Wrap:PVdC is an acronym for its chemical name: polyvinyledene chloride. PVdC wrap is exclusively used for its adhesive purposes. It is also known for impermeability to air and fluids. The aroma of the food lasts longer when reopened after is has been stored either in the freezer or refrigerator. PVdC wrap is also known as saran wrap. (http://www.ehow.com)
  

  

  
  

• LDPE Wrap: LDPE is an acronym for low-density polyethylene. It is known for cling-wrapping food. LPDE wrap is the most common wrap in this era. Name brands that use this wrap include: Saran Premium, Glad Cling Films, and some other common brands. This wrap has, unlike the others, a low clinging ability/adhesion. Despite this fact, it is accepted as a higher-quality product because of its absence of chlorine in its molecules. The food still is freezer safe and microwavable, though.

• Press and Seal Wrap: Press and Seal Wraps are a new and upcoming form of wrap. It uses a special gum-based sealant that creates a perfect seal. The gum-based formula is edible if the films peel off on the food, preventing the food from being toxic. However, the films must be pressed and closed in order to be sealed (e.g. the name of the kind of wrap). This wrap uses special waves of films that flatten when pressed. Press and seal can prevent food from dehydration or freezer burn. The food that is wrapped in this is microwavable. (http://www.ehow.com/)
