Big Brands teaming up on bio-based PET

Many major brands have teamed up to create the plant PET technology collaborative- these companies include brands like Coca-Cola, Ford Motor Co., H.J. Heinz co., Nike Inc., and Proctor & Gamble Co. The collaborative is aimed at accelerating the development and use of plant based PET materials and fibers.

Katherine Schermerhorn, a spokesperson for Coke, states that PTC members are pooling resources, knowledge and experience in an effort to find a sustainable alternative to the use of fossil fuel. The goal is to develop a commercially feasible form of purified terephalic acid made of plant-based sources. PTA makes up 70% of PET formulation by weight. Major companies, including Coke, already use PET made with bio-based monoethylene glycol, the other 30%.

PTC, academic and industry experts are joining forces to develop common, industry wide terminology, practices and standards for using plant-based resin.  Schermerhorn told Plastic News, “We’re coming together to make sure that standards are in place, so when Coke talks about using plant-based packaging it’s the same as when Ford or Heinz or Nike talks about it.”

It needs to be ensured that PET is truly sustainable alternative, and that this will develop supply chains to ensure “feed stock isn’t competing with food supply,” she concludes. Schermerhorn states that because something is plant based it does not mean it is greater in terms of footprint and supply chains. She stresses the importance that they need to develop the trust with customers and consumers.

The development of the PTC have been discussed for a while, it was important for Coke to work with brands that had the same views to environmentally responsible practices, and shared the same vision to drive innovation.

The response to plant based resin has been a positive one, the price predictability on plant based resin is greater than that of resin made of fossil fuels and the environmental advantages have also played a factor in the positive response from customers.

Schermerhorn states that the case for business has to be made for it really isn’t a sustainability movement; Coke has been working for several years on the plant based PET and has been using this technology in its Plant Bottles since 2009.

In December, Coke announced it had planned to make a multi-millions dollar investment in three research companies for the development of a plant based PET bottle by 2020. This investment is a entirely separate form their involvement in PTC, states Schermerhorn.

Bag-in-Box Smart Inventions

“An innovative, flexible packaging that flattens the competition” is the best way to describe CDF Corporation’s bag in box design. The Cheertainer bag in box is a gusseted, form-fit multi-ply bag that is marketed towards chemicals, cosmetics, food & beverage and medical markets. Although relatively new to manufacturing in the Plymouth area, the product goes back to 1995 in Asia, relates Product Manager Iris Thomas. The product is patented and owned by Japan’s Hosokawa Yoko Co.

The Cheertainer bag-in-box holds a wide range of markets, ranging from food & beverages to paints, inks and petroleum. So what is the big draw to Cheertainer? Iris Thomas feels the Cheertainer is a “real hit” because of the sustainability movement, she continues, “it’s a flexible bag, and a replacement to rigid packaging.” She continues, “The bags use less plastic, which translates into saving in warehouse space and transportation, which saves fuel and money,” she says, “they generally have lower cost performance because they’re better in fill and dispensing. It dispenses almost 100 percent of product,” she explains, “There’s not a lot of product trapped in the fold. It’s also safer than rigid packaging.”  In Plymouth, CDF is capable of manufacturing five million bags a year; however the plant is a long way from reaching capacity.

Further advantages to the Cheertainer include, replacing rigid packaging like cube-shaped inserts, cans and plastic pails, the Cheertainer is suitable for semi-automatic and fully automatic lines. The design of the Cheertainer is essentially a flat bag, this design minimizes shipping and warehouse space requirements, the flexibility, and shape minimizes dead space, this allows for more products per pallet. Using the consumer has benefits for using the Cheertainer, the bag fills without using air which eliminates splashing and foaming, the bag has superior seam strength and the fitment is always in the correct position, furthermore the lack of internal folds improves the filling and dispensing of the product- the dispensing if so accurate ranging around 99.9% dispensing of nearly any product.

There’s more to Cheer about!

In the CDF family is Cheer Pack, also deriving from Hosokawa in Asia, a stand up pouch with a cap, good for dispensing yogurts, ice creams and jellies. Cheer Packs President Steve Gosling, has supplied its Cheer Pack to Dole Foods Canada which distributes its five flavors of applesauce in the pouch.

Gosling states, “We produce 1.2 billion pouches a year with this fitting and ninety percent is for children’s products.” The pouches can now be found at seven national food stores, including Whole Foods and Babies R Us. Steve Gosling described the pouches as convenient because of their reclosable application, the no spill advantage and the shelf life of the product is stable for 24 months.

Made with multi-layer laminate material, with an outer layer of polyester which is capable of high-resolution graphic printing, a layer of aluminum foil for excellent barrier properties, another layer of polyester for shock and pressure resistance and lastly, internal layer of polyethylene for direct food contact.

The typical markets for Cheer Pack include energy drinks, beverages, yogurt, and sorbet. Other markets include cosmetics, gels, inks, shampoos, lotions and creams. One of the advantages of the pouches is the tamper-evident, screw on top to ensure safe usage.

CDF intermediate bulk container liners ideal for food grade applications

CDF Corporation offers a full assortment of pillow and form-fit IBC liners for the dairy industry.

Pillow-shaped liners are excellent general use liners for intermediate bulk containers. Used in containers from 100 to 330 gallons, pillow liners offer versatility and value. Pillow liners are typically constructed with two or three plies of linear low-density polyethylene (LLDPE) and a barrier film when used for aseptic and oxygen-barrier applications. When filled, these tote liners form the shape of a pillow. Pillow liners are designed for both viscous and non-viscous food applications.

Form-fit liners offer IBC fillers and end-users an alternative to pillow liners. Form-fit liners are manufactured to form fit the internal shape of your intermediate bulk container. Form-fit IBC (cube-shaped) liners allow easier filling in square or rectangular intermediate bulk containers and provide high performance in critical applications, such as top-fill applications using a bridge or automated filler; containers with no access doors for placing a liner at the bottom; high speed fills and viscous products that would get caught in the folds of pillow-shaped liners. Form-fit liners are designed for liquids and solids.

Intermediate bulk container liners offer many benefits over drums and rigid bottle & cage IBC totes. Freight costs for filled IBC liners in totes are 25% less than drums because the cube shape allows more volume per pallet. Users can also lower freight costs by pairing liners with knock down bins that collapse and are stackable; drums and rigid totes are not collapsible and stackable. Drums and rigid IBCs must be rinsed to be reused, whereas liners keep intermediate bulk containers clean, eliminating container cleaning costs, resulting in immediate reuse of the container. Product purity is essential to maintaining food quality; food grade liners preserve and protect food products. Wide options of filling and dispensing components are also available for liners, which can be customized to meet each end user’s needs.
