Determine the tubing size you need: 
Measure the circumference of the object to be wrapped and add 5%-10%. Divide that number by 2, this is the size of tubing you need. If the size you need is not available, a larger size can be used because the tubing film has a 40% overall shrinkage rate.

75 gauge is used for packaging light products, usually under 12 lbs, and 100 gauge film is recommended for products over 12 lbs, but not over 30 lbs.

Shrink bag provides the easiest, fastest and most economical way to shrink wrap any item including gift baskets. Rectangular, square and dome shape shrink bags are available in different sizes. Shrink bags speed up packaging operation. Ideal for the music, gift basket, publication, soap, candle, crafts and many other industries. The dome shape shrink bags are commonly referred to as gift basket bags are designed specifically for baskets with handles or oval and round baskets. The arc of the shrink bag will fit perfectly around the handle, or bottom without leaving "dog ears". Some users prefer Vent holes in the shrink bags to prevent ballooning, but most users do not like vent holes. Our bags come without vent holes. However, you can easily make vent holes  by yourself if you do need.

Determine the bag size you need. 

Measure the package around its widest point (you get biggest circumference), add 5%-10% to the number and divide by 2 to determine the width (W) of your bag. Measure the package around its tallest point (you get another biggest circumference), add 10% to the number and divide by 2 to determine the height (depth) or length (L) of your bag. If the size you need is not available, a larger size can be used because shrink bags have a 40% overall shrinkage rate.
