It’s good to offer greener options for the very popular flexible packaging in 2021, but it’s even better to offer these materials validated for use with the speed of execution and graphic agility allowed by the digital printing.
Flexible polybag packaging, a green technology manufacturer of plastic film products for flexible packaging and high shrinkage labels, worked with HP Indigo to validate its innovative and fully recyclable Polyphane Pack’N’Cycle packaging films for printing on HP Indigo digital presses.
These films have been sold to companies serving 45% of the European flexible plastic packaging market and used for more than 130 recyclable packaging projects. Sizes include fully recyclable pouches, films and shrink labels that can be found in supermarkets, convenience stores and gas stations around the world.
“The ability to combine our 100% recyclable film with the printing capabilities of HP Indigo enables companies to create packaging that matches their brand while remaining environmentally conscious,” said Yanir Aharonson, CEO of Polysack. “Plastic waste is a major environmental problem and we are happy to help make the world a little greener. “
Polysack’s unique film can replace 70-80% of non-recyclable plastic with 100% recyclable packaging without increasing costs, changing people’s usage patterns or needing to rebuild the infrastructure for packaging production, according to Aharonson.
Printela, a Lithuanian-based flexible packaging converter, chose Polysack’s recyclable film in combination with HP Indigo’s digital printing press (pictured above) to create personalized, eco-friendly packaging.
“Using Polysack’s Pack’N’Cycle films, Printela’s HP Indigo digital sleeve factory efficiently and consistently produces a variety of recyclable sleeves,” said Valdas Buksnys, Managing Director of Printela. “Polysack’s Pack’N’Cycle is an effective polyester (PET) replacement film.
“We are excited to help brands find new packaging options for their products in order to continue improving their sustainability profile,” notes Yair Gellis, manager of flexible packaging development at HP Indigo. “The HP Indigo digital printing solution for flexible packaging provides brands with sustainability benefits, including reduced waste. “
Details and properties of Pack’N’Cycle.
Pack’N’Cycle films are MOPE – mono-oriented polyethylene, Aharonson tells Plastics Today. “These can Be used for a variety of flexible packaging, including lidding films, pouches, packaging packs and many more. Another use is the production of shrink labels for PET containers which can be fully recyclable. This technology is patented and can be used for candy wrappers and almost any flexible plastic wrapper you can imagine. The films have high tensile strength, high gloss, low haze, controlled shrinkage ability, easy and straight opening of the bag, recyclable packaging handles, recycled protective films, etc. The available thicknesses range from 15 to 50 microns. These materials are what we call “recyclability by design”.
According to Aharonson, packaging made using Film Pack’N’Cycle receives the highest recyclability score according to the circular economy and sustainability foundations such as Ellen MacArthur or CEFLEX.
“These materials can be placed in a recycling bin from where they can be collected, then crushed, cleaned and made into pellets that can be reused for the production of plastic products, ”he says.
Packages made from the films have wide applicability.
“We are targeting all flexible packaging markets including pet food, dry food, dairy, pharmaceutical, confectionery, beverage and agriculture ”, Aharonson explains. “Our film can be used for a myriad of plastic packaging including 3 side seal pouches, gusseted bags, upright pouches, spout pouches, zipper pouches, vacuum bags, sachets, flow packs, etc. These categories can be of different sizes and can be used to package different contents such as dry, fresh and frozen foods including vegetables and meat, as well as cement and cleaning fluids.
The size range is just as wide.
“We know our customers use them for one or two gram sachets and for food bags up to 25 kilograms. They can be printed using flexographic, gravure and now digital printing methods.
The films were a resounding success. “The demand for our film has grown by over 350% per year over the past two years. ” Aharonson said.
Films are available worldwide and for any US converter through Polysack’s places of services.
Other advances are to come. “We are currently working on an application of MOPE for lids and for high barrier properties” Aharonson tells Plastics Today.
