Tube Manufacturing Case Study

24th June 2013

Our technical abilities have made Pafra one of the leading adhesives manufacturers in the industry. We have earned our reputation as innovative problem solvers and have an array of pre-formulated adhesives available, and can also create bespoke products to meet our customers’ specific needs. Our production levels mean we can support multi-national brands, as well as smaller operations.

Last year our team met with a multi-national paper converter about an issue they were experiencing. The customer manufactures high quality convolute tubes for the drinks market. The company wanted to reduce the level of tube shrinkage occurring due to water evaporation as the adhesive dried. This meant that caps did not fit well and this was leading to a high rejection rate.

Our technical team carried out an extensive audit and ran trials with the premium product. We identified that their existing product had a low solids content. Excess water was being placed on the paper the tubes are made from, and a high volume of adhesive was being applied in order to achieve the desired level of stiffness.

By offering one of our products that had a higher solids content, the AquaPAL 9560, we were immediately able to reduce shrinking throughout the drying process as there was less water on the paper. We gave the customer a greater level of control and were able to reduce the volume of adhesive required due to the better flow characteristics of our adhesive. The rigidity of the tubes improved as our product dried a lot harder than their previous solution.

Having taken the time to fully assess exactly how the customer’s problem was arising, we recommended one of our existing products, AquaPAL 9560. After introducing our adhesive to their system, the customer was able to increase line speed by over 15%, could reduce their adhesive consumption by 50% and as there was less moisture in the tube, shrinkage was reduced. The cap now fitted better and their rejection rate reduced. The resulting tubes being stiffer, and therefore easier to cut, the customer provided a higher quality finished product.

Envelope Manufacturing Case Study

24th June 2013

Our in-depth understanding of the adhesives industry has enabled our technical team to create a suite of adhesive products that meet a range of requirements. Understanding the capabilities of our products well, we can often recommend a pre-formulated adhesive once we have an understanding of the customer’s specific requirements. We recently worked with a large independent envelope manufacturer based in the UK and by introducing them to an existing adhesive in our product range, we not only saved them money, but also increased their line speeds.

The customer was experiencing wrinkling on the flap gum when working with low cost light weight Manila paper. Our ‘hands-on’ approach meant that the technical team conducted a full audit of the customer’s current production cycle. The line audit involved measuring the distance from the gluing station to the drying station until the end of the production line. We went on to ask a series of questions that allowed us to get to the bottom of how the product was currently performing, and what could be improved. After taking samples of paper, we were able to test a number of our pre-formulated products to determine which one was the most effective.

The AquaPAL 9929 LV was selected as the final product as it was designed to give exceptional lay flat performance. It enabled the customer to coat at a lower rate and prevent the paper from wrinkling. As a result of our process, knowledge and selected product, we were able to significantly reduce machine down time.  Line speed was increased by 15% as the adhesive does not cause crinkling when dried at a faster rate. The customer was also able to reduce the coat weight of the adhesive applied which reduced the cost of production.

Envelope Manufacturing Case Study

28th January 2013

The technical team at Pafra have earned their reputation as innovators within this field, and recent work in the envelope manufacturing sector is evidence of our expertise.

A large independent envelope manufacturer based in the UK came to us as they had developed an issue with wrinkling on the flap gum when working with a low cost, light weight Manilla paper.

After discussion with our expert team and reviewing the options readily available, we were able to recommend our standard flap gum adhesive. This product was designed by our specialists with the primary aim of giving exceptional lay flat performance. We were able to significantly reduce down time and increase line speed as our product is dried at a faster rate. This also enabled the client to reduce the coat weight of the adhesive applied, making it the more cost-effective option.
