Flexible packaging is everywhere. From the coffee pouch you open in the morning to the snack pack you carry in your bag, it’s part of daily life. People like it because it’s easy to use, lighter than rigid packaging, and works for many types of products. Brands like it because it helps protect food, looks neat on shelves, and is easier to ship.

This list is not about hype or marketing talk. It’s a straight look at ten well-known flexible packaging companies around the world. Some are huge global names, some focus more on specific materials or ideas. All of them are active players in food and other packaging markets today.

Quick Overview

Amcor (including Berry Global)

• Country: Switzerland / USA

• Main markets: Food, beverages, pet food, personal care, beauty

• Certifications: BRC, ISO 9001, ISO 50001, ISO 14001, RecyClass, ISCC PLUS

Amcor is one of the largest flexible packaging companies in the world. It operates in dozens of countries and supplies packaging to many of the brands people use every day. If you’ve opened a snack pouch, a coffee pack, or a personal care refill, there’s a good chance Amcor was involved somewhere in the process.

The company has been around for over a century and has grown mostly through steady expansion and acquisitions. One of the biggest recent changes was the acquisition of Berry Global. Berry was already a major player in flexible plastics and films, and bringing it under Amcor made the company even larger and more dominant in food and healthcare packaging.

Amcor focuses heavily on recyclable and paper-based structures alongside traditional plastic films. Instead of chasing trends, the company tends to work closely with large brands that need reliable supply, consistent quality, and global coverage.

Sealed Air

• Country: United States

• Main markets: Food, medical, protective packaging

• Certifications: ColorLogic, ISOQAR, SGS, ISTA

Sealed Air is widely known for protective packaging, but food packaging is a major part of its business. The company works a lot with fresh food, meat, cheese, and medical products that need controlled environments.

It’s a large global company with strong engineering and material science teams. Many of its packaging systems are designed to reduce waste during transport and extend usable life without overcomplicating the pack itself.

Sealed Air often works directly with processors and manufacturers, not just brands. That makes it more of a behind-the-scenes company, but a very influential one in food and medical supply chains.

Biopouches

• Country: China

• Main markets: Coffee, snacks, pet food, frozen food

• Certifications: BPI, TUV, ISO 9001, ISO 50001, ISO 14001, FSC, BRCGS

Biopouches is a medium-sized packaging company that focuses on compostable and recyclable flexible packaging. It works mainly with growing brands rather than global giants, especially in coffee, snacks, and health-related products.

The company offers stand-up pouches, mailers, and custom flexible formats. Many clients choose Biopouches because they want packaging that aligns with eco-friendly goals without moving into overly complex materials.

Biopouches sits in a space between small custom suppliers and large multinationals. That makes it appealing to brands that want flexibility, lower order volumes, and more direct communication.

Tetra Pak

• Country: Switzerland

• Main markets: Food, beverages, supplements

• Certifications: FSC, RSB, ASI, ISO, DQS

Tetra Pak is best known for carton packaging, but its work still fits within flexible food packaging discussions. The company focuses heavily on liquid foods like milk, juice, and nutritional drinks.

What sets Tetra Pak apart is that it doesn’t just sell packaging material. It also provides filling machines and full packaging systems. That makes it a long-term partner rather than just a supplier.

Tetra Pak mainly works with large food producers and beverage companies. Its packaging is built for scale, consistency, and high-volume production.

Earthycores

• Country: China

• Main markets: Paper packaging, food, beauty, wellness, pet products

• Certifications: BPI, TUV, ISO 9001, ISO 50001, ISO 14001, FSC, BRCGS

Earthycores focuses on paper-based and fiber packaging, with a strong emphasis on paper tubes and compostable solutions. The company serves brands looking to move away from plastic-heavy packaging.

Its products are common in food, cosmetics, herbal products, and lifestyle goods. Earthycores works closely with brands that care about how the packaging feels in hand, not just how it performs on shelves.

The company is not a global giant, but it has carved out a clear role in paper-focused flexible packaging. That clarity helps it stand out in a crowded market.

Smurfit Westrock

• Country: United Kingdom

• Main markets: Food, beauty, industrial

• Certifications: FSC, PEFC, ISO 9001, ISO 14001, ISO 45001, FSSC 22000

Smurfit Westrock was formed after the merger of Smurfit Kappa and WestRock. Together, they created one of the largest paper and packaging groups in the world.

The company works across both paper and flexible-style packaging, serving food brands, industrial companies, and consumer goods manufacturers. Its size allows it to handle large contracts and global supply needs.

Smurfit Westrock is more about scale and reach than niche innovation. It’s often chosen by companies that need reliable packaging across multiple regions.

ProAmpac

• Country: United States

• Main markets: Food, healthcare, pet, eCommerce

• Certifications: AIB, BRC, FSSC, GMP, ISO 9001, ISO 13485

ProAmpac is a fast-growing flexible packaging company that expanded quickly through acquisitions. Despite being younger than many competitors, it has built a strong presence in food and pet packaging.

The company focuses on custom flexible films and pouches, often working with brands that need specific sizes, barrier properties, or shipping-friendly designs.

ProAmpac positions itself as a problem-solver rather than just a supplier. That approach has helped it gain market share in a short time.

Mondi Group

• Country: United Kingdom

• Main markets: Retail, industrial, eCommerce, pet care

• Certifications: ISO 9001, ISO 14001, ISTA, FSC, PEFC

Mondi Group operates across both paper and flexible packaging. It serves retail brands as well as industrial and shipping customers.

The company has a strong presence in Europe and works with businesses that need packaging for transport, storage, and online sales. Pet food packaging is also a growing part of its portfolio.

Mondi is known for balancing industrial-scale production with material development, especially in paper-based flexible formats.

International Paper

• Country: United States

• Main markets: Food, grocery, shipping, personal care

• Certifications: FSC, PEFC, SFI, ISO 9001, ISO 14001, B Corp

International Paper is one of the oldest packaging companies on this list. While paper is its main focus, flexible-style packaging still plays a role in its food and shipping solutions.

The company works closely with large retailers, food producers, and logistics companies. Its strength lies in scale, long-term contracts, and supply reliability.

International Paper is less about niche packaging trends and more about keeping global supply chains moving smoothly.
