Converting Today Adhesive Feature

 

Nick Smith, Managing Director, Parkside Flexibles

 [1] Can you point to any adhesive technologies that are having a particular impact across brands at the moment? 

Current packaging trends are highlighting a need for re-closable features to be integrated into existing packaging formats with demand for this type of functionality growing. Consumers and brand owners alike are looking for solutions to address these trends, such as sustainability, portion control, and frustration free openings.

In order to meet these needs Parkside, have invested heavily in laser scribing technology, this solution has allowed us to create easy open and re-closeable features whilst replacing the costly tear strips and zips. The laser can be used to create an integral opening of any size, shape and position as a part of the standard pack design.

 

[2] How important to brand owners and their converter partners is it to choose the right adhesive for their packaging application?

Absolutely critical. The adhesive cannot not affect the packing line in terms of speed of sealing nor be inconsistent in its sealing performance. Leaking packs are expensive for the entire supply chain and with the current media focus on product contamination and hygiene; the adhesive becomes an important consideration in pack design. In particular, adhesives used to manufacture re-closable packs must easily peel and reseal but also have the initial lock seal performance of standard non-re-closable solutions.

 

[3] Is bio-degradability now a vital component of the adhesive component of today’s packaging? 

Sustainability considerations are certainly driving innovation. In the U.K we see a significant focus on the recyclability and compostability of packaging. Adhesive systems must be compatible with these processes. We are also seeing bio-degradability and compostability credentials becoming more important to consumers. Parkside are the first flexible packaging company to produce a compostable triplex laminate structure which has been awarded the Vincotte accreditation for home compostability. This was an industry first and groundbreaking for Parkside, this would not have been possible without a suitable adhesive which met the requirements of the rigorous testing procedure and offered the functionability of a barrier laminate.

As a company, we’re continuing to evolve our compostable products to include other secondary packaging solutions in the Parkside portfolio such as Rockpockets®, which would be compostable at the end of the service life.

These successes mean that environmentally aware brand owners, packers and retailers finally have the choice of flexible packs that can be disposed of by consumers, avoiding landfill and without any detrimental effect on the environment.

 

[4] How are brand owners and converters balancing the need to have a robust seal, yet allow easy opening and closing for consumers? 

As discussed above, there are certainly challenges with easy open and re-closable solutions. Prior to any launch Parkside ensure all products undergo a demanding testing procedure to ensure packs are fit for purpose and fulfil the expectations of both the brand owner and the consumer. Parkside work closely with the brand owner to ensure the correct material / adhesive combinations are used to achieve the required shelf life. Products undergo rigorous transit testing after line trials to ensure the packs retain the robust seal required.

Another consideration for re-closable packs is tamper evidence. How does the retailer ensure the pack contents haven’t been tampered with prior to purchase if the pack re-closes? Again Parkside have worked hard to combine technologies and clever functional print solutions to develop a tamper evident solution that gives both the retailer and consumer the confidence they can have both convenience and safety.

 

[5] How are the challenges of food safety, structural packaging and sustainability being met from an adhesives perspective? 

 For packaging manufacturers, enhancing safety and sustainability is key for the packers without in any way compromising on performance.

At Parkside we used food safe pressure sensitive adhesives – which are water based or solvent free. When combed with high performance films we are able to offer a wide range of materials which offer extended product shelf life.

Our drive is to constantly develop and deliver even better and safer products and services with a smaller environmental footprint that meet the demands and needs of our customers.

 

[6] What does the future of packaging adhesives look like from your perspective?

Feedback from packaging manufacturers and brand owners alike suggests that there will be further take-up of reseal technologies in the future.

With our laser scribing technology, we can reduce the pack manufacturers’ costs, increase line speeds and ultimately reduce the carbon footprint of packs. Our designs also give shoppers better flexibility for when and how much they eat, reducing food waste through improved storage and portion control.

Although reseal technology is something that consumers like to have, the signs are that it could become the must-have for the future.
