Is Paper A More Sustainable Flexible Packaging Material Than Plastic? (Forbes.com)

Like many other major plastics applications, plastics use in flexible packaging has come under deep scrutiny in recent years as sustainability concerns rise and spread globally.

Paper is often lauded as a far more environmentally friendly alternative but how do the two materials really compare? And what is the most sustainable solution?

Historically, papers have been used in flexible packaging for many applications, including confectionery, pet food and dried food. By the early-2000s, however, paper demand as a flexible packaging substrate began to decline due to competition from down-gauging and the rise of plastic alternatives.

Consumers today widely view paper as a more environmentally friendly alternative to plastic. A European consumer preferences survey, commissioned by Two Sides in 2020, concluded that 62% of consumers see paper and cardboard packaging as better for the environment. Additionally, 70% of consumers surveyed said they were actively taking steps to reduce their use of plastic packaging.

Comparing green credentials isn’t as straightforward as some would think, however.

Paper is far more biodegradable than plastic and very easily recycled. But it often ends up in landfill, where its degradation rate slows – while it takes up more space than the same weight of plastic. Additionally, paper-based flexible packaging is often laminated with plastic/aluminium or coated with resin, therefore becoming non-recyclable.

Plastic’s properties make plastic packaging ideally suited for efficiently containing and protecting products during shipment and delivery to customers. However, despite its advantages, plastic is made of a non-renewable resource, whereas paper is made of trees. Furthermore, plastic can be recycled but it is currently difficult to achieve high levels of post-consumer recycled content in plastics due to post-consumer waste contamination.

Packaging Corporation Of America Announces Conversion Of Jackson, AL Mill Paper Machine To High-Performance Virgin Linerboard

Packaging Corporation of America announced that it has discontinued production of uncoated freesheet (UFS) grades on the No. 3 paper machine at its Jackson, AL mill and will begin preparing for the permanent conversion of the machine to linerboard. As previously disclosed, in order to meet strong packaging demand and maintain appropriate inventory levels, the machine temporarily began producing linerboard in the fourth quarter of 2020 and continued producing linerboard in the first quarter of 2021. The mill will now begin preparations to permanently convert the 365,000 ton-per-year No. 3 UFS paper machine to a 700,000 ton-per-year high-performance, virgin kraft linerboard machine, in a phased approach, over the next 36 months. Plans are for the machine to run at its current containerboard production rate for the next 12 to 15 months until the scheduled first phase outage is taken in the second quarter of 2022.

Pregis announces new film converting, equipment assembly facilities to support growth of its Sharp Packaging Systems brand

Pregis announces its new film converting facility in Elkhorn, Wisconsin, and new machinery assembly facility in Germantown, Wisconsin to meet growing e-commerce demands for its Sharp Packaging Systems® by Pregis brand of poly bagging solutions. Production has been moved from nearby East Troy, doubling the number of converting lines. The facility converts multilayer coextruded polyethylene film (which has been blown at its Sussex, Wisconsin facility), into pre-opened bags supplied on a roll or in a box. The bags are used with Sharp Packaging bagging equipment at fulfillment centers to package and ship a broad variety of soft goods, pharma/nutraceuticals, and other non-fragile products. The high-output equipment only requires a small number of operators, enabling packers to social distance. To support the increased demand for equipment, Pregis is also moving its equipment assembly operations from the current Sussex, Wisconsin facility to a new location in Germantown, Wisconsin in Q2. This move enables more efficient assembly layout, double the production space to support current and future growth, and allows additional space for further expansion of its poly converting capacity at the current Sussex facility.
