How to Correctly Use and Securely Lock A Bag Seal

(Models PS-360 and DTZIP)

Both PS-360 and DTZIP seals have multiple uses.  This article is specifically about use on bags.

Bags that require security seals are mostly used for money, valuables, documents or bulk products that need protection from theft or contamination.

Common (plain bag) types are made of plastic or fabric and are sealed using a plastic band security seal that is wrapped around the top of the bag and tightened (cinched).  Some bags have “eyelets” or holes near the top for threading a seal then pulling it tight to close.  More commonly on reusable bags.

PS-360 is an all plastic flat band security seal with about 8 inches of useable band (strap).  It has a unique multi-point plastic lock mechanism that is very strong, and resistant to tampering.  An added feature is a tab for securely attaching an information tag with the seal, if needed.   

DTZIP is also a plastic pull up security seal with about 16 inches of useable band, and a unique stainless steel locking tab.  The tab passes completely through slots in the band making an exceptionally strong hold that cannot be reversed.  DTZIP also features a larger “flag” portion with room for more printing and highly readable custom marking, like logos and barcodes.

Both models are available with optional Gripping Teeth, for additional hold on most bags.  Or with smooth band (designated NT, for No Teeth) usually for bags with eyelets, or bags that could be damaged by sharp teeth.

TIGHTENING IS KEY

For optimal security, the seal band should be pulled as tightly as possible without damaging the seal or the bag.  Proper tightening avoids accidental or intentional movement of the security seal.  And it deters unauthorized access with tools to manipulate the lock mechanism.  The seal must be cut off to open the bag.

Locking by hand is normally enough to secure our bag seals.  But there are tools on the market (typically used for plastic cable ties) that can assist with tightening.  If you have any questions or concerns about locking procedures contact us or your AC&M vendor.

TRIM THE EXCESS BAND   

Once the seal is fully tightened you should cut the excess band (no longer needed) as close to the lock body as possible.

Some users prefer to leave the excess band on the seal to verify it is all still intact.  This is not necessary if the seal is fully tightened.  Once the seal is tight and the excess seal band gone there is no practical way to re-attach the seal after removal.  There is not enough of the band remaining to pull it around the bag and re-insert it.

SEALING SMALLER BAGS

If a bag is too small for a tight fit when fully closed, the bag often can be twisted and folded over to double the diameter that is being sealed.  If you have special needs or difficulty using our standard seals contact us or your AC&M vendor.

MARKING and PRINTING

Both models can be marked with letters and serial numbers.  Stock pre-stamped seals have SEALED and numbers.  Custom stamping and/or printing of logos and barcodes is possible.  We can use hot stamp, laser, or durable roller print. The DTZIP security seal has more space and more options for marking, making it a better choice if you need extensive custom print.  We highly recommend a thorough record keeping program and careful inspection whether using stock or custom marking.    (See Recommended Best Practices for detailed handling recommendations.)
