Shrink Wrappers, or Bundlers, are used to package a collection of products as one, supported or unsupported, by applying a shrink film around the bundle and then shrinking the film to the products. 

Automatic shrink wrap bundlers offered by Liquid Packaging Solutions apply a "bullseye" wrap around products.  The machines create a sleeve of shrink film which is secured around the product, leaving two circular openings, or bullseyes, on the sides of the wrapped product.  The machines can shrink wrap individual products, trays or products, pads of products or unsupported collections of products.
