LPF flexible packaging and the shift toward high-barrier laminates
What LPF flexible packaging means today
LPF flexible packaging is best read as an industry and company reference, not as a universal material grade. Public company history and trade coverage identify LPF Flexible Packaging B.V. as a Dutch flexible-packaging business in Grootegast that became part of SÜDPACK in 2021. As of September 2026, the public identity connected with LPF is SÜDPACK Grootegast, which SÜDPACK describes as a competence center for high-barrier laminates.
For packaging buyers, the practical question is not only who LPF was. It is what that laminate expertise represents: product protection, shelf-life support, printability, form-fill-seal performance and the difficult move from complex barrier structures toward packaging designs that can better meet recycling and EPR expectations.

LPF as a company name, not a generic packaging standard
In public flexible-packaging sources, LPF is used mainly as the name of LPF Flexible Packaging B.V., formerly based in Grootegast, the Netherlands. It should not be confused with resin abbreviations such as PE, PP or PET, or with measured barrier properties such as oxygen transmission rate and water vapor transmission rate. If a supplier uses LPF in a specification sheet, buyers should ask whether it means the former company, a proprietary structure, an internal product code or a separate term defined by that supplier.
Trade publications reported that SÜDPACK acquired LPF Flexible Packaging B.V. from the Clondalkin Group, with the transaction taking effect on February 1, 2021. SÜDPACK’s own company history lists the 2021 acquisition of LPF in the Netherlands and presents the site today as SÜDPACK Grootegast. The strategic rationale was straightforward: LPF added experience in printed and unprinted duplex and triplex laminates, especially high-barrier films for sensitive products.
| Date or period | Publicly reported development | Packaging relevance |

| February 1, 2021 | SÜDPACK acquired LPF Flexible Packaging B.V. | Expanded SÜDPACK’s high-barrier laminate capability. |
| 2021 onward | The Grootegast operation has been presented as SÜDPACK Grootegast. | Positioned as a competence center for high-barrier laminates. |
Why the LPF story matters for high-barrier flexible packaging
High-barrier flexible packaging is designed for products that are sensitive to oxygen, moisture, aroma loss, grease, light or contamination risk. The barrier requirement depends on the product and the supply chain. Dry snacks, coffee, spices, pet food, healthcare products, confectionery, seeds and technical goods may use similar pouches or reels, but they do not necessarily need the same laminate.
LPF’s importance came from the kind of work associated with the company: duplex and triplex laminates, printed films and structures built for demanding protection. A duplex laminate usually combines two layers, while a triplex laminate combines three. These structures may include sealant layers, print webs, barrier layers, paper, aluminum, metallized films or specialized coatings. The advantage is performance tuning. The drawback is that mixed-material structures can be harder to recycle in conventional systems.
SÜDPACK Grootegast’s public product information continues to emphasize high-barrier laminates and flexible formats for food and beverages, confectionery, healthcare, pet food, industrial and agricultural applications. That range helps explain why searches for LPF flexible packaging are often less about one product and more about a capability profile: combining barrier performance, print, lamination and pack format selection for sensitive goods.
Formats and material choices associated with the Grootegast operation
Public SÜDPACK Grootegast pages describe both printed packaging and preformed packaging. The printed packaging area includes mono-materials and multilayer films, with materials such as kraft, polyethylene and polypropylene. The same public materials state that printed packaging can be produced from multiple mono-material options and a broad library of laminated concepts, using flexographic and gravure printing methods. These details matter because the printing process, ink system, substrate and lamination sequence can affect pack appearance, sealing behavior, migration risk and recyclability claims.
The preformed packaging area includes stand-up pouches, shaped bags and sachets. These are familiar flexible-packaging formats, but their performance depends heavily on structure. A stand-up pouch for a dry food product may need stiffness, puncture resistance and good shelf presentation. A sachet for sauce, spice or seed may put more weight on portion control, hermetic sealing and barrier performance. A shaped bag may be chosen for brand differentiation, but it still has to run reliably through filling, sealing and distribution.
| Publicly described area | Typical packaging role | Key buyer question |
|---|---|---|
| High-barrier laminates | Protection for oxygen-, moisture- or aroma-sensitive goods. | Which barrier value is required for the real shelf-life target? |
| Printed PE films | Sealability, freezer suitability and use in laminate concepts. | Is the PE structure mono-material, laminated or part of a mixed-material pack? |
| Printed PP films | Confectionery, salads, flowers and other applications where clarity, stiffness or machinability may matter. | Does the PP film match the filling line’s heat-seal window and speed? |
| Kraft-based films | Natural paper look, branding and selected food, household or agriculture uses. | Is the pack truly paper-recyclable, or is paper only one layer in a laminate? |
| Stand-up pouches and sachets | Retail display, portioning, lightweight distribution and product protection. | Can the format balance shelf impact with end-of-life requirements? |
The sustainability trade-off around barrier laminates
Flexible packaging has a real resource-efficiency argument. The Flexible Packaging Association has noted that flexible pouches can use substantially less plastic than comparable rigid containers in some applications, with lower material use and distribution advantages. That point matters because sustainability is not only about whether a package is easy to recycle. It also includes material input, product protection, food-waste prevention, transport efficiency and damage reduction.
At the same time, high-barrier flexible packaging can face a recycling problem. Many structures that protect products well are multilayer or multimaterial, and those designs may not fit cleanly into existing collection, sorting and recycling streams. This is the central tension for the laminate market associated with LPF-type expertise: a pack can reduce material use and protect the product, yet still perform poorly against recyclability criteria if its layers cannot be separated or processed at scale.
The Sustainable Packaging Coalition’s 2026 trends work highlights the growing influence of producer responsibility organizations and regional rules in defining what counts as recyclable or sustainable. That matters for flexible packaging because design teams can no longer rely on a broad claim that a pack is recyclable in theory. Increasingly, they must consider whether a package is collected, sorted and recycled in practice in the markets where it is sold.
Regulation is adding urgency. The European Union’s Packaging and Packaging Waste Regulation entered into force in February 2025, with rules beginning to apply in phases from August 12, 2026. EU communications state that requirements for all packaging to be recyclable and for mandatory recycled plastic content in new plastic packaging will apply from 2030, subject to detailed rules and exemptions. In California, SB 54 sets 2032 goals that include making covered packaging recyclable or compostable and achieving a 65 percent recycling rate for single-use plastic packaging and plastic food service ware. These policies do not automatically ban high-barrier laminates, but they do make design-for-recycling evidence more commercially important.
Food-contact and chemical-safety issues buyers should not overlook
Many LPF-related and high-barrier flexible packaging applications involve food, pet food, healthcare or other sensitive products. For these markets, performance is not limited to oxygen or moisture control. Materials must also be suitable for the intended contact conditions, including food type, filling temperature, storage time, sterilization or pasteurization, freezing, reheating and exposure to fats or acids.
In the United States, the Food and Drug Administration treats many substances used in food packaging as food contact substances. The FDA states that industry is responsible for ensuring food contact substances are safe and comply with legal requirements. The agency also reviews certain food-contact authorizations and may reassess substances when new scientific information becomes available.
One example is the FDA’s continuing review of phthalates in food-contact applications. In 2022, the agency revoked authorizations for 23 phthalates after a petition showed those uses had been abandoned. On May 27, 2026, the FDA released a scientific evaluation related to grouping certain still-authorized phthalates for possible future cumulative risk assessment. For flexible-packaging buyers, the lesson is broader than one chemical family: migration, additives, adhesives, inks and recycled-content claims all need documentation, especially when packaging directly or indirectly contacts food.

- Request a food-contact declaration matched to the intended market, not a generic letter.
- Confirm the intended food type, temperature range and contact duration used in testing or compliance assessment.
- Ask whether inks, adhesives, coatings and sealants are included in the compliance review.
- For recycled content in food-contact packaging, confirm whether the source and process are authorized or supported by applicable regulatory review.
- Keep artwork, formulation and supplier changes under change-control procedures.
How to evaluate an LPF-related high-barrier flexible packaging specification
A useful specification should connect product risk, machine performance, regulatory compliance and end-of-life expectations. A laminate name alone is not enough. Two packs can look similar on shelf but have very different barrier values, seal layers, adhesives, print systems and recyclability outcomes.
Start with the product. Does it lose flavor through oxygen exposure? Does it cake when moisture enters? Does aroma retention matter? Is the product greasy, acidic, powdered, sharp-edged or sterilized? These details determine whether a simple mono-material film is realistic or whether a more complex barrier structure is justified.
Then test the packaging process. Flexible films have to unwind, register, form, fill, seal, cut and pack at commercial speed. A more recyclable film that fails on the packaging line is not a solution. Buyers should ask for evidence around seal initiation temperature, hot tack, coefficient of friction, puncture resistance, laminate bond strength and print durability where relevant.
| Evaluation area | What to ask | Why it matters |
|---|---|---|
| Barrier performance | What are the oxygen and water vapor barrier targets under defined test conditions? | Barrier values change with temperature, humidity and structure. |
| Machinability | Has the film been trialed on the intended VFFS, HFFS, pouching or lidding equipment? | Line speed and seal reliability can decide commercial viability. |
| Food contact | Which regulations, declarations and migration assumptions apply? | Compliance depends on application, geography and contact conditions. |
| Recyclability | Is the pack mono-material, recycle-ready, recyclable in selected markets or only theoretically recyclable? | Policy and EPR fees increasingly depend on evidence, not slogans. |
| Claims | Can sustainability, recycled-content or compostability claims be substantiated? | Unverified claims create legal and reputational risk. |
For brands comparing legacy high-barrier laminates with newer recycle-ready structures, the strongest approach is staged validation. Test the simpler structure first, but do not ignore shelf life, abuse resistance or food-contact constraints. If performance falls short, document why a barrier layer or laminate complexity is needed and whether downgauging, mono-material redesign or alternative coatings can reduce impact without compromising the product.
What the LPF case says about the flexible packaging market
The LPF story reflects a wider market pattern. Specialist converters with expertise in lamination, high-barrier films and demanding pack formats have become strategically valuable because brand owners need more than commodity film. They need structures that protect products, run efficiently, print well and stand up to scrutiny from regulators, retailers and consumers.
However, the market is moving away from treating performance and sustainability as separate tracks. A modern flexible-packaging brief should ask for both. The winning structure is not always the thinnest, the most recyclable-looking or the highest-barrier option. It is the structure that meets the product’s protection requirement with the least unnecessary complexity, while giving the brand defensible compliance and end-of-life information.
That is why LPF flexible packaging remains a useful search topic even after the LPF name became part of SÜDPACK Grootegast. It points to a practical question facing the sector: how can high-barrier laminate know-how be adapted for a packaging economy shaped by EPR, recyclability definitions, food-contact scrutiny and pressure to reduce material waste?
Frequently asked questions
Is LPF flexible packaging a type of material?
Public industry and company sources mainly use LPF as the name of the former LPF Flexible Packaging B.V., not as a generic material category. If LPF appears in a supplier document, ask the supplier to define it clearly before treating it as a technical specification.
What happened to LPF Flexible Packaging?
SÜDPACK acquired LPF Flexible Packaging B.V. in 2021. The Grootegast site is now presented publicly as SÜDPACK Grootegast and is associated with high-barrier laminate capability within the SÜDPACK Group.
Are high-barrier laminates recyclable?
Some may be designed for specific recycling streams, but many traditional high-barrier laminates are difficult to recycle because they combine different materials. Recyclability depends on the exact structure, the market, collection access, sorting behavior and whether recycling happens at scale.
Is mono-material flexible packaging always better?
No. Mono-material design can improve recyclability potential, but it must still protect the product and run on packaging equipment. If a mono-material film leads to product spoilage, seal failures or distribution damage, the overall sustainability result may be worse.
What should buyers request from a high-barrier flexible packaging supplier?
Buyers should request barrier data, food-contact documentation, seal and machinability information, structure details, change-control procedures and evidence supporting any recyclability, recycled-content or compostability claims. A complete specification reduces risk far more than a material name alone.
