Why Use Vapor Barriers

Darren Kincaid - Tuesday, May 25, 2010

In cold climates, insulation alone is not enough to keep our costly heat from escaping. Given the slightest opportunity our precious heat will find its way out in an alarming way.

Once we understand the principle that warm air is attracted to cold air, and not the other way around, it should become almost a matter of pride to keep that warm air in!  Although some heat is lost by conduction through the insulation, most of the heat loss in a building is through air movement, or air infiltration, through the walls.

That's where vapor barriers come in. A vapor barrier – also known as vapor retarder – is merely a continuous sheet of impermeable material installed on the inside, i.e. the warm side of the wall, and it's designed to keep the warm air from escaping through or around the insulation and other building components.

There are several reasons for wanting to keep the warm air inside the house through a vapor barrier installation; among them:

  • Energy efficiency
  • Heating costs
  • Preventing the deterioration of the building materials (wood, insulation) by moisture (hence the alternate term moisture barrier). In winter, as the heated air meets the cold air, it creates condensation, which is water of course. The vapor barrier is designed to prevent this phenomenon from taking place.
  • Health problems caused by molds

Stretch Wrap Basic FAQs

Darren Kincaid - Tuesday, May 11, 2010
What size do I need?
First, you need to answer whether are you applying the stretch wrap by hand or with automated equipment.  If you are stretching the film by machine, you will generally use a film over 20" high and 5000 or 6000 feet long. These rolls are heavy -- about 32 lbs. Since that's a little too much to carry around a pallet, most people use 18" x .80 x 1500' rolls to stretch their pallets by hand. If your skids are not very high or if you just need to wrap the top and bottom of the loads, you could use 15" or 12".

Maybe you have seen stretch wrap used to bundle things like millwork, plastic pipe and small boxes. This is called bundling stretch wrap. It's used like tape, but it won't stick to the product or leave residue. This wrap comes in 2-6" sizes.

Can I use stretch wrap for covering my food?  NO!!! Stretch wrap is not made for food contact and this industrial product should be kept away from children. Like any plastic, it can be dangerous.

Is stretch wrap recyclable?  Yes, stretch wrap can be recycled through many local and state recycling centers.

Recycling Logos for Plastic Bags

RECYCLING LOGOS

20 years ago an American group came up with a numbering system to make it easy to recycle. If you mix them up recycling becomes tricky.   The most useful ones for poly are:

Low density polyethylene
- used in packaging bags, grip seal, carrier bags, bin liners and heavy duty sacks.



High density polyethylene
- some carrier bags and bin liners.



Polypropylene
- used for display bags including flower bags and greetings cards.

Advantages of CAST Stretch Film

Darren Kincaid - Monday, April 19, 2010
Why is some stretch film called CAST and some BLOWN? Is this plastic or gum?

Originally, all stretch wrap was blown, a process much like blowing bubble gum. Resin is heated and passed over an opening through which air is blown. Most state-of-the-art film today is cast. It is extruded through rollers and "laid out" in sheets. This process allows the film to be made in multiple layers. The layers allow the film to be made with cling on only one side. This optional one-sided-cling film is great where you don't want one pallet to stick to the one next to it. Also, these films layers can make the film stronger by adding tough layers to the inside. Cast film is also clearer and quieter coming off the roll.

Do I need Shrink Wrap or Stretch Wrap and what is the difference

Darren Kincaid - Saturday, April 10, 2010
Do I need Shrink Wrap or Stretch Wrap and what's the difference?

Most people who order stretch wrap from us call it shrink wrap ..  but the products are very different. Shrink wrap film is made from polyolefin plastic, while stretch wrap is made from polyethylene plastic. Shrink wrap is generally used to protect a single product, such as the plastic over toys at the toy store or CD's when you first buy them. Shrink wrap gets its tight seal through a heating process. The product is wrapped and heated with a hairdryer-like tool or put through a heat tunnel. Shrink wrap can also be used for bundling products together, such as bottles of soda. We supply both stretch wrap and shrink wrap.

Stretch wrap is generally used to hold boxes on a pallet for transport. Stretch wrap is pulled around the load and stretched. The plastic has a memory and wants to return to its original size. This "elastic band effect" holds the load tight.
