| Bag production problems - Poeton Coating seals it | 11th March 2004 |
A hard wearing, non-stick Apticote coating from Poeton Industries has eliminated the need for a costly PTFE tape, reduced machine downtime and saved energy, for bag manufacturer Parkside International.
Barnsley based Parkside International specialises in the latest bag-making technologies for the food and personal care markets, producing Wicketted, Windle and Draw Tape Bags for products as diverse as bread, fresh produce, wet wipes and disposable nappies.
During the high-volume bag manufacturing process, heated sealer heads are used to close parts of the bags. To prevent the plastic material sticking to the heads, Parkside had been applying a special Teflon/PTFE tape. However, whilst the tape was effective it was also expensive and caused frequent machine hold-ups as it needed replacing after a sealing run of just six hours.
Parkside spokesman Steve Bradley says the company needed to find a more cost-effective alternative to the tape and contacted Poeton.
Says Poeton's Trevor Amos: "We recommended Apticote 810TP, a hard wearing, non-stick coating that is particularly suited to packaging applications. An initial trial on the sealing heads in just one machine, proved so successful that Parkside is now running coated heads on two machines and planning to use them on the remaining two machines in the near future."
Six months later, Steve Bradley reports that Apticote 810TP has substantially improved the efficiency and productivity of the two machines by eliminating the downtime needed to replace tape every six hours, as well as eliminating the cost of the tape itself. There is also a useful reduction in energy costs, as the coated heads are able to operate at a lower temperature - down from 170oC to 150oC.
He adds that the sealing heads have been running on both machines without problems, and operators are reporting that plastic residue from the process that used to stick to the tape, is now easily wiped from the Apticote coated heads.
Summing up a significant hidden benefit of Apticote versus tape he says: "Within the company there is also increased confidence in the bag sealing process across the range of products and we believe this will also result in greater customer confidence."
