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 Gummy Glue?
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 glues?
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 appreciate.

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.
