Sustainability remains as one of the label and package printing industry’s most critical topics. All levels of the supply chain are exploring ways to reduce their materials’ carbon footprint and foster recyclability. This is especially true with films.

“The latest trends in film labels are heavily focused on sustainability, circularity, and significant gains in efficiency and productivity,” says Angel Harvey, director of marketing, Film, Rapid Roll, Avery Dennison. “There is a strong push for enabling recyclability, incorporating recycled content like 90% rPET liners, and advancing circular solutions. Technologies such as AD CleanFlake are leading the way by enabling the recycling of rigid plastic packaging and addressing critical gaps in recycling stream compatibility.”

According to Avery Dennison, sustainability and recycling are central to the company’s R&D efforts. The focus is on developing recyclable materials, thinner liners, and expanding the use of recycled content.

“Converters are increasingly requesting solutions that prioritize sustainability, customization, and performance,” states Harvey.

There are needs beyond sustainability, too. In addition to sustainability, film labels are valued for their unmatched durability, flexibility, and aesthetic appeal.

“Features like the ‘no-label look’ for clear films and water/moisture resistance make them ideal for industries such as home care, personal care, food, and beverages,” remarks Harvey. “Innovations like Global MDO Next Generation are leading the market as the only semi-conformable films with APR recognition that float during the PET recycling process.”

Working through challenges

There are numerous challenges with sustainability, though. There is a limited global infrastructure for recycling release liners. Plus, matrix waste remains a significant hurdle.  Material compatibility represents another challenge.

Suppliers like Avery Dennison are working to ensure recycled materials work seamlessly with coatings and adhesives without degrading performance.

According to Harvey, the goal is to balance performance and sustainability. “We’re developing linerless systems and multi-layer constructions that meet both environmental and functional requirements,” she explains. “Avery Dennison also addresses these challenges through initiatives like the AD Circular program, which connects converters and brands with trusted recycling providers to improve landfill diversion and support circularity.”

Paper vs. Film

Many converters are tasked with the decision of utilizing paper or filmic substrates, depending on the application and need. When assessing the facestock, paper labels are a cost-effective and versatile choice, making them ideal for low- to medium-speed applications. While easier to cut, they perform well in standard roll-to-roll setups. 

“Film labels offer superior, more precise diecutting, especially for complex shapes,” comments Harvey. “Their strength and flexibility prevent tearing and ensure cleaner edges, which is crucial for high-speed, automated applications where durability and precision are key.

“Film labels are preferred for applications requiring flexibility and aesthetics,” she continues. “They excel in creating a ‘no-label look’ and resisting water and moisture, making them ideal for home care, personal care, food, and beverage applications. For flat or simple-curved containers, BOPP is a great choice. For squeezable containers, our Global MDO semi-squeeze material is the perfect fit.”

When dealing with liners, paper liners are best for low- to medium-speed applications. According to Harvey, paper liners provide excellent diecutting performance and sustainability through certifications like FSC and PEFC. They are also versatile and work seamlessly with most standard labelers. 

“PET film liners are used for high-speed and precision applications due to their strength, moisture resistance, and dimensional stability,” adds Harvey. “They are particularly effective in humid or harsh environments, and offer recyclability after dispensing.”

Newest films

Most recently, Avery Dennison has launched a range of films. Avery Dennison has expanded its CleanFlake Technology Portfolio, which now features 2.0 Mil Cavitated White BOPP constructions for improved PET recycling. In addition, Avery Dennison’s Global MDO Next Generation represents a semi-squeezable film offering with an enhanced print surface, better clarity, and PET recycling compatibility. 

The company’s metallized films with AD CleanFlake Technology have been recognized by the Association of Plastic Recyclers (APR) for HDPE and PET recycling, as well. Finally, Avery Dennison’s 90% rPET Liners have been optimized for pharmaceutical, wine, and spirits applications, advancing eco-friendly packaging solutions. 

“Avery Dennison supports converters by offering an extensive portfolio tailored to diverse application needs,” says Harvey. “We provide technical expertise to help customers select the right film facestock for optimal performance and shelf appeal.”
