How long has
Lock n’ Pop been around?
Q: How is Lock n’ Pop different than other
liquid cold palletizing adhesives?
A: Most other liquid cold adhesives are nothing more than
diluted glues or pressure sensitive materials (sticky)
originally intended for other uses. Lock n’ Pop is designed
specifically for palletizing boxes, bags and frozen or chilled
packages. Lock n’ Pop is a water-based adhesive that forms a
chemical bond with package surfaces that holds firm until it’s
time to un-stack the pallets. Unlike other adhesives, Lock n’
Pop does not leave a sticky residue or harm package surfaces. It
is invisible upon package separation. Application is easy and
requires low maintenance.
Q: How is Lock n’ Pop different than 3M
A: Gummy Glue is a 100% solid adhesive that is applied at
265 degrees Fahrenheit, and leaves a gummy residue on the
packaging surface that must be manually removed in order to
achieve a clean package surface. In contrast, Lock n’ Pop is a
water-based adhesive that is applied cold, eliminating the
danger of burns. And Lock n’ Pop is invisible upon package
separation, eliminating the need to "remove" anything.
Q: My stretch wrap or hot melt products
seem to be working fine. Why should we change to Lock n’ Pop?
A: Just because something is working does not mean it cannot
be improved upon. Lock n’ Pop increases the stability of pallets
when used either alone or in conjunction with stretch wrap. By
utilizing Lock n’ Pop, you can significantly reduce shipping
damage and improve internal efficiency, while minimizing hazards
to employees and improving the environment.
Q: How is Lock n’ Pop different than hot melt palletizing
A: Even though there have been improvements in hot melt
palletizing glues over the past few years, they do not come
close to working as well as Lock n’ Pop. Unlike hot melt, Lock
n’ Pop does not leave any visible residue. Lock n’ Pop is much
less susceptible to package tearing upon separation. Also, Lock
n’ Pop is applied cold. Accidental contact with the applicator
or the adhesive will not cause burns. If you care about how your
packaging looks at its point of final destination, you should
give Lock n’ Pop a try. It is, simply, the best solution.
Q: What are the deficiencies of using stretch wrap?
A: Stretch wrap or film attempts to contain the load by
placing exterior stress or pressure on the outside surface area
of the unit load. This pressure can deform packaging and cause
packages to lose integrity and collapse. Box strength is
primarily concentrated in the corners of the box. In order to
maximize strength while stacking, boxes require very good
alignment. Stretch film does not maintain alignment of cases.
During transportation, tier shifting occurs within the wrapped
load and causes the box corners to come out of alignment. This
can result in boxes collapsing under the weight of the load. In
contrast to stretch film, Lock n’ Pop works by bonding each box
in the unit load together, thereby maintaining alignment of the
cases. This eliminates the need for exterior wrap compression,
and preserves the look and integrity of the boxes.
Q: Do I have to buy special equipment to apply Lock n’ Pop?
A: Several companies make equipment that can be used to
apply Lock n’ Pop and we also manufacture and sell our own
specially designed equipment. We offer many equipment options
available to Lock n’ Pop customers, including affordable lease
and rental packages in addition to outright purchase.
Q: Is Lock n’ Pop easy to clean up?
A: Yes. Because Lock n’ Pop is water-based removing it from
equipment or other items is extremely fast and effortless. The
Lock n’ Pop adhesive won’t clog machinery or create any type of
mess in the packaging process, even when wet. Lock n’ Pop
eliminates the mess of typical hot or cold glues.
Q: Is Lock n’ Pop environmentally friendly?
A: Lock n’ Pop is extremely safe for the environment. It is
a non-toxic, water-based adhesive that is biodegradable.
Packages shipped using Lock n’ Pop can be recycled as before.
Lock n’ Pop produces zero waste (nothing to bundle, store or
dispose of), a benefit that your customers are sure to
Q: Does Lock n’ Pop have volatile organic compounds (VOCs)?
A: No! All of Lock n’ Pop’s formulas are free of VOCs,
meaning there are no EPA restrictions to worry about in your
palletizing process. No VOCs ensure a healthier workplace for
you and your employees.
Q: Is it safe to ship food products using Lock n’ Pop?
A: Yes. Under the Food and Drug Administration’s Code of
Federal Requirements (volume 21, section 175.105), Lock n’ Pop
ingredients are approved for indirect contact with food.
Q: Can Lock n’ Pop be customized to meet specific customer
palletizing and shipping needs?
A: Absolutely. Most Lock n’ Pop customers will benefit from
one of our several standard formulas. However, in some cases
customized formulas are required to meet unique palletizing
needs. In every case, we ask that customers supply us with a
sample of their package so that we can match the right formula
to the package type. This is a free service that we provide.
Q: How long has Lock n’ Pop been around?
A: Lock n’ Pop has been in business since 1965. Lock n’ Pop
palletizing adhesives have been sold for the past 20 years, with
over 200 million pallets shipped using Lock n’ Pop. Several of
the advanced formulas were developed during the past two years,
and our R&D lab is continually working to improve our product
offerings in order to assure our customers that they are
utilizing the best solutions for palletizing in the ever
changing world of packaging.
