Innovia Films has been supplying biaxially oriented polypropylene (BOPP) films to the packaging industry for over 45 years under its trademark, Propafilm. The company explains how ease of opening is now as big a priority for consumers as barrier properties.
Propafilm is made using a unique 'bubble' process that guarantees balanced orientation and properties. This enables Innovia to create BOPP with superior clarity and exceptional gloss, which make it ideal for packaging.
The films also have outstanding mechanical, balanced shrink qualities and high stiffness. Its additional coating capabilities ensure that Innovia can offer a comprehensive range of films, fit for any requirement or application, however demanding.
Propafilm RCP, peelable BOPP film, is now available in 52 and 60µm. This significantly proven, easy-to-open, food packaging material now includes heavy-duty, high-barrier and snap wrap options.
Propafilm RCP's chief benefit is that its seals are easy to open. Consumers of all ages and abilities can simply peel them back to reveal the product inside, with no excessive force required. Scissors and sharp implements are unnecessary, eliminating the risk of serious injuries as well as the 'wrap rage' experienced when packs prove difficult to get into.
From a product packer's point of view, achieving this easy opening could not be simpler: the seal strength is consistent every time and the film can be used on existing packaging machines without any adjustments being required.
Another key benefit of using Propafilm RCP is that product spillage can be hugely reduced. With traditional films, opening containers often results in tears to the packaging. Who has not spilled pasta or dried fruits, when opening a bag, scattering the precious contents? Propafilm RCP provides reliable clean and neat opening, without destroying the pack. In addition, because the pack remains intact, resealing is an option when a label is applied.
Amaia Cowan, Innovia Films' market development manager, packaging, states: "Brand-owners are waking up to the fact that easy-open is increasingly becoming a major purchase consideration for consumers, especially those with reduced dexterity.
"Innovia Films has listened to consumers who have complained about the difficulty of getting into conventional packaging: its easy-to-open packaging makes their lives that little bit easier. Rest assured, these films continue to protect the products they wrap, while providing an enhanced product experience."
Propafilm RCP films have been designed and developed using proven technology. The acrylic coating ensures a broad sealing range, which enables a wide packaging operating window and good machinability in all standard formats (flow wrap, vertical form seal or overwrap). Their moisture and aroma barrier properties make them an ideal choice to preserve many food items, including dried and chocolate-based products.
Innovia also offers films for bundling or transit collation. It is essential that outer films do not stick to inner films, so that they can be removed without damage to inner unit packs.
Two solutions are available. One is acrylic-coated film, which does not seal to coextruded films; the other is new coextruded films, which offer a low seal threshold, avoiding heat sealing to the inner packs. These materials can allow lightweighting by replacing traditional outer packaging on cartons. An exceptional pack appearance is assured, with high visibility of the unit packs inside.
"Innovia has developed a range of BOPP filmic overwrap solutions, ideally suited to applications where multiple product packs are collated and shipped to retailers, who then split the collation pack down to display the individual packs," says Cowan.
Innovia will be at Interpack in Düsseldorf on 4-10 May on stand F04 in Hall 9. The team will be geared up to discuss new products, developments and technology.
"Development is always ongoing," says Cowan. "Innovia is close to revealing some interesting products that meet specific needs in the market place. Interpack is its first opportunity to share some insights."
