The Scotch® Bag Sealer P400 is a compact, tabletop unit that seals most film bags quickly and efficiently using pressure sensitive tape to form an adhesive-to-adhesive flag seal. After the bag is sealed, a trimmer slices through excess bag length for neat, professional results. This useful device can be mounted for stationary use or be fitted with a weighted base, sold separately, for portability.The Scotch Bag Sealer P400 provides fast, tight sealing of most film type bags. In one follow through movement, a single strip of pressure-sensitive tape circles the neck of the bag to form a "flag-type" seal. Sealing your bags with pressure sensitive tape using the P400 is an efficient and effective way to secure the contents against pre-mature bag opening, damage and loss. The neat, secure seal also helps reveal evidence of tampering or pilferage and increases the safety of bag contents.
