As companies strive for further cost saving and reduction in plastic packaging volumes Gransden respond. “2019 has been an exciting year for Gransden and our Lock N Pop product offering. Customers now need to reduce stretch film and save money, we continue to satisfy both requirements with Lock N Pop” Duncan Potter Managing Director, Gransden PLP Ltd.


Gransdens Lock N Pop continues to offer a solution for plastic packaging reduction. With new installations in the drinks, food and industrial sectors during 2017 and 2018, Gransden has helped reduce plastic usage whilst improving pallet stabilisation.

“Typically companies are finding that they can achieve their objective of reducing plastic packaging with Lock N Pop, AND, reduce operational costs at the same time. Less cost and less plastic is the win:win our customers need”  Duncan Potter – Director Gransden UK Ltd.

Customers continue to benefit from the cost saving benefits of Lock N Pop pallet stabilisation adhesive. A further year of double digit sales growth has been driven by the significant savings made in operating costs at some of the UKs leading beverage and industrial production facilities following their adoption of the Lock N Pop pallet stabilisation technology.

As customers seek to find innovative solutions to their distribution processes, Lock N Pop yet again proves that financial, environmental and operational cost savings can be made with Gransdens solutions.

W&H Marriages and Sons Ltd (www.marriagesmillers.co.uk) is a proud independent miller and has been producing flour since 1824. It operates from a site in Chelmsford where space is very much at a premium and it needs to stack pallets of bags of flour several layers high after production and before they are shipped to its customers.

Mill Manager, Phillip Bunn, wanted to ensure that Marriages’ pallets were stable in storage and transit so that its customers could be confident that every delivery would be 100% complete and undamaged. Stretch wrap alone did not seem to be sufficient so he approached Gransden Packaging Line Products (www.gransden.org) for advice.

Gransden is the exclusive UK distributor of Lock N’ Pop pallet stabilisation systems and recommended that Marriages install a two headed automatic in-line system. This system applies a controlled quantity of Lock N’ Pop adhesive to Marriages’ bags. This adhesive is water based and has a high shear but low tensile strength which fixes the pallet load for lateral movement but enables easy lifting of bags from the pallet.

Because of the unique formulation of the Lock N’Pop adhesive the bags themselves are undamaged when the bags are separated by the customer.

The Lock N’ Pop system has been running for over 6 months now and Phillip is delighted. He says: ‘I am really impressed by the stability of our pallets; customer feedback has been positive and we are seeing no damage to our product in transit to the customer.’

Massey brothers is a family owned manufacturer of a wide variety of animal feeds and agricultural products with 125 years experience in the animal feeds business.  The company operates from two manufacturing sites located at Preston in Lancashire and Holmes Chapel in Cheshire. Additionally, the company sells its products through three company owned cash & carry outlets located at Longor and the two manufacturing sites in Preston and Holmes Chapel.

The company manufactures around 27,000 tonnes of bagged feeds a year and the business is experiencing steady growth in demand for it’s products.

The company has been quick to adopt new technologies and processes in order to increase it’s performance and has completely removed the need to stretch wrap outbound products by switching to use “Lock n’ Pop” stabilisation adhesives to stabilise palletised loads.

What was the issue?

  • The main aim was to remove the process step of stretch wrapping palletised loads which was increasing the loading time for distribution vehicles
  • The company was also seeking ways to reduce packaging spend without compromising product quality

What the company did

Animal feeds are sold in various pack formats but mainly in plastic sacks weighing 25 kg.  Palletised loads weigh 1 tonne. A semi-automated wrapping machine was used and palletised loads had to be physically moved from the end of the production lines in each plant to the wrapping area prior to wrapping.  The wrapping operation utilised 25 micron stretch film which was applied to the load in 12 wraps around the standard pallet.

The company considered alternative wrapping methods and materials before deciding to trial water based stabilisation adhesives.  Following successful trials the company adopted this method of stabilising it’s products.  The only capital requirement of the change was installing the required spray equipment in-line at the point of palletising the load.

The spray installation did not take up much space and as the adhesive is applied cold there is a minimal energy cost to operate the spray applicator.

Once the water based adhesive is applied it quickly dries securing the sacks in place.  The high shear strength of such adhesives holds the sacks in place during distribution but easily releases packs when picked from the load.

What was achieved?

Since switching from stretch wrapping of loads to using ‘Lock n’ Pop’ stabilisation adhesives the company has achieved it’s primary objective of streamlining the palletisation process by cutting out the need to stretch wrap it’s loads.  This has reduced overall production time by 5 minutes per tonne.

The most impressive achievement has been the near total removal of stretch film from the operation.  If stretch film was still used today the volume of film used would be:

27,000 pallets x 12 wraps x 4.4metres = 1,425,600 metres, 25 micron film weighs approximately 12g per metre so the weight of film saved is=17.1 tonnes per annum

The benefits of switching can be summarised as:

  • Estimated film saving of 17.1 tonnes a year
  • Estimated Saving of 1011 cores weighing 1.2Kg each = 1.2 tonnes of cardboard
  • Carbon emission reduction of 34.2 tonnes p.a.
  • Adhesive gives a significant saving against film
  • Reduction in manufacturing time
  • Pallet stability maintained
  • Increased convenience for customers who do not have to dispose of waste film.

LOCK N’ POP has conducted a controlled trial of pallets stabilised with a LOCK N’ POP system versus those stabilised with stretch wrap alone. Not unsurprisingly pallets stabilised with a LOCK N’ POP system are significantly more stable than others. Check out the video above or click here.

Users of LOCK N’ POP systems:

  • save money: less or no stretch wrap and other packaging materials;
  • reduce product damage; and
  • produce less plastic waste which must either be recycled or sent to landfill

Here’s an overview of what LOCK N’ POP products do, where they can be used and who are typical customers. LOCK N’ POP customers benefit in 3 ways:

  • they save money: no more stretch wrap or other pallet wrapping materials;
  • their palletised products are better protected in storage and transit; and
  • they are not giving their customers a plastic waste management headache.
