TWIST & WRAP
recyclable paper wrappers can help maintain a more tradition perception of a brand. Finally, recyclable metallised paper wraps can give bright new and modern look. Jonas concluded by mentioning a UK-based
confectionery manufacturer that needed to ensure it was able to comply with the latest packaging materials recycling guidelines set by one of its biggest customers. The manufacturer wanted to find a replacement for its originally used wax-based paper twists. “We suggested the new certified recyclable and repulpable PaperTwister as a good solution and this has worked well. Not only did it meet the packaging guidelines, but it also worked as a drop-in solution on the existing twist lines, meaning the manufacturer was able to use the new twist material on its existing lines without any change in the efficiency of the equipment.”
A popular choice According to research from Zion Market Research, twist wrap has maintained its position as the most popular packaging choice, being used worldwide for chocolate, candy, toffees, lollipops, chewing gum, and bakery goods. As already reports, there are a large selection of twist wrap materials available on the market. Polysack offered a run down on some of the main twist wrap raw material choices that have been available through the years: PVC: A commonly used polymer in the
past. Its main disadvantage, however, is its environmental impact which is mainly due to the decomposition of the polymer which releases environmentally damaging chloride ions. For this reason many confectionery manufacturers no longer use PVC and are switching to alternative raw materials. Cellophane: A polymer derived from
renewable sources, making it a sustainable packaging material that supports the circular economy and it is entirely biodegradable. On the downside, it is a costly raw material, and so in the confectionery sector its use is usually limited to premium products. Polyethylene terephthalate (PET) and polypropylene (PP): These polymers have found applications in the packaging industry and are theoretically suitable for recycling. However, because they are not widely used in all sectors, it is rarely actually recycled Polyethylene (PE): PE is a thermoplastic polymer with a variable crystalline structure and is one of the most commonly used plastic in food industry packaging applications. As
such, PE has a dedicated recycling stream. Polysack provides PE-based twist wrap film
for individual candy and chocolates, which can be integrated into any PE mechanical recycling process in most countries in the world. The films are said to demonstrate all the properties needed for twist wrap applications, including mechanical strength and dead-fold, which is one the most important properties required of a film used for twist wrap applications. Dead-fold refers to a measure of the ability of the packaging material to retain a fold or crease. Polysack’s Polyphane PE-based twist wrap film is characterised by high elasticity, when compared to comparable PP or PET films, so it is able to tightly wrap a product, without any sagging, and providing more hermetic product protection. Moreover, it is based on high density polyethlene (HDPE), which offers good vapour protection, making it well suited to use in confectionery applications.
Facing a dilemma According to Amaia Cowan, Business and Development Manager at Futamura, brand owners today are faced with the dilemma of choosing the right twist wrapping material need to consider the overall performance that these materials provide them with. Will they run efficiently on existing lines? Will they
sufficiently protect the product? Are they attractive and eye catching? Can they easily be opened, even by their younger consumers? And, ultimately, what is the end-of-life option of the material and is this end-of-life option realistic today? “The combination of technical properties and the end of life of our NatureFlex films make them a good choice for confectionery twist wrap applications,” said Amaia. “The cellulosic films have inherent dead-fold and static-free properties. The films also run well on both old and new packaging machines.” NatureFlex cellulose-based films form a family of bio-based and compostable films that have been designed to offer flexible packaging solutions. Most grades are produced with a minimum of 90% renewable raw materials and individual films are BPI and TUV certified for compostability. It is important to note that compostable materials need oxygen, moisture, and microorganisms to allow the degradation process to take place. As such, a compostable material will be shelf-stable and will not break down until it is placed into a compost environment. The principal raw material of NatureFlex
is cellulose, derived from wood pulp sourced from responsibly-managed forests and it contains no GMO ingredients. The films are essentially a form of transparent paper, with
Will they run efficiently on existing lines? Will they sufficiently protect the product? Are they attractive and eye catching? Can they easily be opened, even by their younger consumers? And, ultimately, what is the end-of-life option of the material and is this end-of-life option realistic today?
