Many shops find their packing supplies inventory is in dire need of a shrink wrapping heat gun. These propane powered guns make the shrink wrap process a breeze. Many people only associate shrink wrapping with items you purchase in the store like CDs and DVDs. But shrink wrapping as an enhancement to your packing supplies can give sensitive items such as computer monitors or circuitry an extra layer of protection in transit.
Computer boxes are frequently shrink wrapped before shipping; you may wish to use the same precautions in your own operation by adding shrink wrapping to your packing supplies.
