Two film launches expose the real barrier to mono-material flexible packs

Two film suppliers announced new products within days of each other this month, and neither was a headline-grabber on its own. Looked at together, though, they point at the same unresolved problem in flexible packaging: the features that make a pouch work on the shelf and in the kitchen are often the reasons it can’t be made from a single, easily recycled polymer.

American Packaging Corporation (APC) and Dow introduced LinearEdge, a machine direction-oriented polyethylene (MDO-PE) film built for a cleaner tear. Innovia Films introduced Propafilm CHBM, a metallised biaxially oriented polypropylene (BOPP) film built to replace aluminium foil in high-barrier laminates. One fixes a consumer annoyance; the other fixes a recycling-compatibility problem. Both are attempts to close the gap between what mono-material packaging can currently do and what converters and brands actually need it to do.

What’s new

APC spent nine months working with Dow on a monomaterial polyethylene that offers consumers a cleaner tear. The target is a familiar complaint: a perforation that rips past its intended line, into the zipper or the body of the pouch, leaving the pack impossible to reseal. Jeff Travis, APC’s senior manager of innovation and sustainability, said the goal was to develop something that was real simple and easy to implement without adding additional steps to the manufacturing process. Dow’s Michelle Sauder framed the engineering problem as balancing the new tear feature against everything else a laminate has to do, asking how do we optimize the easy-open feature, but not compromise on the food protection and the toughness and all of the other things that a package has to be designed to do. APC says it sees an “urgent” need for this product in confectionery, snacks and beyond.

Innovia’s Propafilm CHBM is aimed at a different pain point. Innovia Films has introduced Propafilm CHBM, an ultra-high-barrier metallized biaxially oriented polypropylene (BOPP) film designed as an alternative to aluminum foil in flexible packaging structures. The new film is engineered for polypropylene-based laminates, supporting the development of recyclable mono-material packaging while providing protection against oxygen and moisture, with target applications including food packaging, stand-up and flat pouches, and other formats requiring high barrier performance to preserve freshness, aroma and product quality. It’s supplied in an 18-micron (0.72-mil) gauge, combining oxygen and water vapor barrier properties with high optical density, strong metal adhesion and thermal stability. Innovia’s Alasdair McEwen said the film enables our customers to simplify packaging designs without compromising product protection.

Why foil and bad tear lines are a recycling problem, not just a quality one

Aluminium foil has long solved barrier problems that polymers struggle with on their own. The cost is recyclability: aluminium foil has traditionally delivered strong barrier properties in flexible laminates, but its presence alongside polymer layers complicates recycling because the materials cannot be separated economically. A pouch that is otherwise mostly polypropylene gets knocked down a recyclability grade, or out of the recyclable category altogether, because of a foil layer that might be a fraction of its total weight.

Tear performance sounds like a pure consumer-experience issue, but it has a design consequence too. Converters have sometimes reached for laminations with non-PE films, directional scoring, or added layers specifically to control tear propagation, each of which can push a pack’s composition below the polyethylene-purity thresholds that recyclers use to classify film as readily recyclable. A film that delivers a clean tear within a single PE structure removes one more reason to reach for a mixed-material build.

Where the recyclability bar actually sits

In North America, the relevant yardstick is the Association of Plastic Recyclers’ Design Guide. For PE flexible film, APR’s preferred category requires the package to be compatible with flexible film collection streams and easily recycled into a variety of end use applications at a composition of more than 90% (by weight) of PE flexible mono-material. RecyClass, the European scheme that both brands and recyclers increasingly treat as the reference point for flexible film, works on a similar principle: the only option to obtain a class A or B is to follow a mono-material approach with at least 90% of recyclable plastic content, no matter the recycling stream. Non-PE layers, including tie layers, metallised coatings and foil, are assessed individually and can drop a structure out of that top tier even at low add levels, which is why APR and RecyClass have spent the past few years working through specific layer types, including alignment with natural PP design guidance, tie layers that are fully compatible with PE film recycling and defining blue tints in PET.

Under the EU’s Regulation (EU) 2025/40 (PPWR), that same logic is written into law rather than left to voluntary design guides. From 1 January 2030, packaging placed on the EU market will need a recyclability grade of A, B or C, with the regulation’s longer-term timetable pushing to “recyclable at scale” by 2035 and to grades A or B only from 2038. For flexible packaging, that trajectory points in the same direction as APR and RecyClass: fewer layers, less non-polyolefin content, and functional additions like barrier coatings or tear features that don’t compromise the dominant polymer’s recyclability classification.

Supplier	Product	Base polymer	Problem it targets	What it typically replaces
Dow / American Packaging Corp.	LinearEdge	MDO-PE	Uncontrolled tear past perforation, poor reseal	Multi-material laminates added for tear control
Innovia Films	Propafilm CHBM	Metallised BOPP	High oxygen and moisture barrier without foil	Aluminium foil in PP laminates

What packaging teams should actually check

A launch announcement is not a recyclability certificate. Before specifying either film, or any comparable product, packaging engineers and sustainability managers should confirm a few things separately.

Independent design recognition. Check whether the specific structure, not just the film in isolation, has been through APR’s Critical Guidance Protocol or carries a RecyClass certification. A film can be “recycle-ready” in concept while the finished laminate still needs testing once it’s combined with inks, adhesives and sealant layers.
Functional equivalence, not just barrier numbers. Oxygen transmission rate and water vapour transmission rate figures from a data sheet describe the film, not necessarily the shelf life of a specific product after retort, sterilisation or long-distance transport. That testing is on the converter and brand.
Where the film is actually collected. A PE or PP film pouch is only as recyclable as the collection system it reaches. In most of the US, flexible film still relies on store drop-off rather than curbside collection; in the EU, collection and sorting infrastructure for flexible plastic packaging is still being built out ahead of the PPWR’s 2030 grading requirement.
Cost and line compatibility. Both companies describe their new films as drop-in replacements that don’t require new equipment. That claim is worth validating on your own lines, at your own speeds, before committing a SKU.

The other route: thinner barriers on paper, not plastic

Not every converter is betting on mono-material plastic. Rapids Paper + Packaging recently expanded commercial availability of its Ecova Barrier platform, a heat-sealable paper designed for applications requiring protection from moisture, oxygen, or grease, aimed at dry foods such as cereals, rice, grains, and pasta; dry mixes and powdered food products; frozen fruits, vegetables, and other freezer applications; snack applications.

Paper-based flexible packaging faces its own version of the same trade-off, though. Unilever’s global head of packaging, speaking to the scale of the challenge, noted that right now, paper is the only widely recyclable and compostable packaging material on the market, but on its own, it’s insufficient: it has low barrier properties, it rips easily in industrial production settings, and it doesn’t melt, which makes sealing the pack extra challenging. Many paper-based solutions today, the same source noted, often require a thin layer of plastic film to provide barrier protection and seal and protect what’s inside. In practice, this probably means paper-based flexibles will keep facing the same layer-by-layer scrutiny that plastic laminates do, just measured against repulpability rather than APR or RecyClass film categories.

Open questions

Neither LinearEdge nor Propafilm CHBM has, as far as our research found, a published APR Design Recognition or RecyClass certificate yet; both are being described in launch terms as “recycle-ready” or supporting mono-material structures, which is a claim about intent and compatibility rather than a completed third-party assessment. It’s also unclear how either film performs economically against the multi-material structures it’s meant to replace, since neither company has published pricing. And collection capacity, not film chemistry, remains the binding constraint on whether a mono-material PE or PP pouch actually gets recycled once it leaves the shelf, in the US or the EU.

What to watch next

Watch for APR or RecyClass design recognition filings tied to either film over the coming months; that’s the point at which a supplier claim becomes a verifiable packaging decision input. Watch too for how the European Commission’s pending delegated and implementing acts on packaging design for recycling criteria treat metallised films and barrier coatings specifically, since the detail of those acts, still outstanding as of October 2026, will decide exactly how forgiving the PPWR’s grading system is toward structures like these.

What to do now

Ask any film supplier for the specific APR or RecyClass status of the finished laminate you intend to run, not just the base film.
Build functional testing (barrier retention after your actual process conditions, tear force, reseal cycles) into any trial before switching a SKU.
Map which of your flexible SKUs rely on foil or non-polyolefin layers purely for tear control or cosmetic opacity; those are the easiest near-term candidates for a mono-material swap.
Track your relevant collection infrastructure, store drop-off in the US, kerbside sorting capability in your EU markets, since a recyclable structure with nowhere to go doesn’t help your PPWR grade in practice.
