Paper packaging is taking up new frontiers. Possibly you’ve seen paper throughout new codecs comparable to pet food canisters, vitamin combine containers and even staples in your liquor cupboard.
Shoppers love paper packaging for its perceived environmental advantages, recyclability and renewability. They’re even questioning: Why can’t all my packaging are available paper?
Traditionally, paper packaging was restricted by worth and efficiency constraints that gave plastics and different supplies an edge. However now, paper-based packaging has grown to make up about 46 p.c of the world packaging market. As extra manufacturers proceed the shift towards “paperization,” there are three key steps they will take to make sure their paper packaging delivers on efficiency, client belief and sustainability.
The KIND bar case research
Snack bars have historically been the area of foil wrappers or plastic pouches. However that’s beginning to change. Lately, Mars’ KIND Snacks model launched a nationwide pilot of a paper-based wrapper for his or her snack bars — a bundle utilizing How2Recycle pre-qualified paper materials designed to be curbside recyclable, and aligned with KIND’s aim of making certain all packaging is designed for recyclability by 2030.
The pilot, at present operating in choose Complete Meals Markets throughout eight states, is a crucial step, however nonetheless it’s not a full transition. Sturdiness of the brand new packaging by means of transportation and the power of the paper substrate to take care of product shelf-life are essential, as is curbside recyclability. All of those challenges took time and collaboration to beat.
So, how did KIND Snacks overcome them? They began small. They began by gathering foundational insights on the packaging’s sturdiness and efficiency — insights that they took again to their R&D groups earlier than launching the present nationwide pilot. Collaborators labored to make sure the packaging can be certified by How2Recycle as “broadly recyclable,” which means it may be collected curbside for recycling in most communities.
This case underscores the promise and the complexity of paper-based packaging. Whereas the advantages — recyclability, renewability and alignment with sustainability targets — of paper-based packaging are clear, they arrive with trade-offs. To construct client belief and understanding, clear and constant messaging about fiber sourcing and recyclability stay important.
As we will see from KIND, there are a number of actions companies can take to reap the advantages of paper packaging. Right here’s a have a look at three:
1. Collaborate on progressive codecs
Working intently with their provider, Printpack, to handle the challenges of switching to a brand new materials was essential to the profitable launch of the KIND Snacks’ paper wrapper. The businesses collaborated to create a packaging format that met required product performance, comparable to preserving shelf life, whereas additionally delivering a format designed to be recycled in curbside assortment applications.
To sort out shared challenges comparable to recovering new paper codecs, the packaging {industry} should scale collaborations comparable to these between KIND and Printpack — shifting past particular person efforts to unlock collective influence.
Organizations are already coming collectively to assist enhance finish markets for recycled fiber and enhance the restoration of progressive packaging codecs. Take the Polycoated Paper Alliance for example. The coalition of name house owners and packaging producers is working to advance restoration for generally used objects comparable to paper cups, ice cream containers and versatile paper pouches. The group addresses particular technical challenges such because the sortation of polycoated paper in materials restoration amenities and acceptance in neighborhood recycling tips.
2. Analysis excellent challenges
Different main hurdles for paper packaging may be addressed by researching current sustainability and recyclability challenges. For instance, shoppers typically suppose that meals residue on packaging — comparable to grease on a pizza field — makes the packaging not recyclable. The work of particular person organizations, comparable to Smurfit Westrock’s research on pizza bins, has proven that meals residue contamination could also be much less problematic than generally perceived. Nonetheless, broader analysis into these and different hurdles to paper packaging, comparable to recyclability, sturdiness and product shelf life, can assist manufacturers switching to paper shut the efficiency hole.
The paper packaging {industry} can observe comparable analysis efforts throughout different packaging supplies, such because the plastics sector’s analysis into “clear and dry” requirements for recyclability, which search to determine clearer steering for the way clear and dry packaging must be to really be recycled. Constructing on this analysis mannequin, the Sustainable Packaging Coalition’s Paper Packaging Recyclability Collaborative is finding out How2Recycle label’s affect on shoppers’ willingness to wash meals residue off paper packaging.
Addressing lingering challenges would require sustained, industry-wide collaboration and a unified method to analysis and client steering.
3. Commit for the long-haul
At a current SPC sustainable packaging occasion, main packaging corporations PaperWorks, Billerud and Progressive Changing confused a essential distinction between paper and packaging: funding. With many years of innovation and investments behind plastic packaging’s barrier applied sciences, it units a excessive customary that many paper options are nonetheless working to fulfill.
So how does paper get on par with the efficiency traits of different packaging supplies it’d exchange? How do progressive paper applied sciences get to price parity with supplies which were available on the market for much longer? How do manufacturers understand the advantages of paper and constructive buyer response? The reply lies in long-term dedication and cross-industry collaboration.
Manufacturers comparable to KIND Snacks are main the best way with their pilot, however exterior of the meals house, different main packaging gamers comparable to Amazon and Microsoft are equally committing to transition as a method to fulfill their sustainability targets and enhance buyer expertise.
Paper’s potential relies on collective motion
Switching to paper packaging presents challenges — however for manufacturers dedicated to creating the swap, the trail ahead is obvious. With daring commitments, open collaboration and a willingness to sort out the powerful questions collectively, manufacturers can speed up paper innovation, earn client belief, and switch sustainability targets into tangible progress.
