During a PACK Expo keynote in 2006, Walmart launched the packaging scorecard initiative. Since then, brands have been continuing to update and revise their packaging to create a more environmentally-friendly solution. Below is an outline of how the sustainable initiative has impacted the food industry across various package types, including paper-based, plastic, glass, and aluminum.
RELATED: Taking the Eco-Friendly Packaging Leap
Paper and paper-based products, such as cartons and paperboard, are easy to recycle, and the resultant recycled material is extremely versatile. More than half of Americans have easy access to paper recycling — an amount which is expected to increase rapidly — and there are far fewer restrictions on recycling paper than plastic.
For applications such as food safe packaging and high-end brand displays, coatings are utilized to provide the appropriate properties. To achieve a recyclable, paper-based package for these types of applications, water-based coatings are often required.
To address this, Sierra is working with nationally-recognized chemical companies to qualify reliable eco-friendly coatings. Our water-based, eco-friendly coatings can meet biodegradable, compostable, and fully recyclable requirements. These coatings also possess important properties to aid in brand awareness efforts; they are easy to print over and allow for optimal packaging aesthetics.
One of the biggest challenges with recyclable, plastic packaging is the restrictions involved with recycling plastic material. It is estimated that 95% of recyclable plastic packaging, amounting between $80 and $120 billion worth of packaging material, is wasted on an annual basis.
While outreach, recovery, reclamation, and recycling efforts can be effective for multinational corporations, they may be cost-prohibitive for smaller or regional brands. For these businesses, investing in eco-friendly packaging is often a more practical, actionable solution.
Recycling plastic presents a three-fold problem:
Aluminum, Glass and Plastic Bottles
As demand rises for sustainable products, brands are prioritizing green initiatives, such as eco-friendly packaging and packaging recovery.
The Coca-Cola Company, for example, has established an extremely ambitious recycling initiative — by 2020, they aim to recover and recycle a full 75% of the beverage containers, bottles, and cans they produce annually. Working with The Recycling Partnership, Coca-Cola has already recycled 59% of their output.
This is just one example of the growing sentiment in favor of environmentally conscious initiatives; worldwide, consumers are looking to brands to lead conservation efforts with sustainable, environmentally friendly packaging options.

Investing in environmentally-friendly packaging is quickly gaining momentum in many industries, including food and beverage. From a product development perspective, our paper experts have seen biodegradable packaging become increasingly popular.
According to the Environmental Protection Agency (EPA), a material can be described as biodegradable when it is “capable of being decomposed by the action of biological processes.”
In other words, a material is biodegradable if it will decompose within a reasonable amount of time when left outside in natural conditions.
RELATED: How to Choose Between Biodegradable, Compostable, and Recyclable Packaging
Glass, commonly used for packaging beverages and various high-end products, is not biodegradable. In fact, it can take up to 1,000,000 years to biodegrade. Plastics are not biodegradable, either; polyvinyl chloride (PVC), often used in food and beverage applications, is capable of physical breakdown but never truly decomposes. Polyethylene (also known as polythene or simply “poly”), another popular food packaging plastic, takes up to 1,000 years to biodegrade. Other plastics can take various lengths of time to biodegrade, averaging at about 450 years.
These packaging decomposition rates are untenable when striving for increased sustainability. Paper, on the other hand, is an ideal biodegradable option, taking anywhere from two to five months to decompose.
Because the terms are often incorrectly interchanged, biodegradability and compostability are frequently conflated. Adding to the confusion is the fact that the processes involve the same action — decomposing a material into an organic state. This decomposition occurs in two very different ways, however.
Compostable materials decompose only when in a carefully controlled environment, where factors such as source material, moisture content, temperature, oxygen levels, and acidity are all closely monitored. Biodegradable materials decompose through a chemical process where micro-organisms break down the materials resulting in carbon dioxide, methane, and biomass.
Paper is much more biodegradable than plastic or glass. Some paper can decompose faster than fully organic products. For example, paper towels often biodegrade quicker than thick fruit rinds such as orange or banana peels. However, it’s important to keep in mind that not all paper products biodegrade at the same rate.
Less processed papers, such as mechanically pulped products, biodegrade at slower rates than more highly processed papers. Paper containing mechanical pulp has higher amounts of lignin — very complex phenolic polymers found in the cell walls of trees — which interferes with biodegradation.
The right coating can provide resistance to grease, oil, water, oxygen-exposure, or a combination of these food-safe properties for paper-based packaging; while maintaining the eco-friendly standard. However, these types of properties are often provided by poly- or PVC-based substrates, thereby negating any of the potential environmental benefits of using paper in packaging.
To counter this issue and create truly environmentally friendly packaging, Sierra Coating Technologies has partnered with some of the nation’s most accomplished chemical companies to develop several biodegradable coatings.
As a leading contract and toll manufacturer of eco-friendly coating and lamination solutions, including poly and PVC replacements, Sierra is proud to be a part of the push toward sustainability. The benefit of working with Sierra is that we run tests on our production equipment to ensure the materials and substrates will run efficiently during a full-line production.

The need for paper coating is on the rise with online shopping as one driver in this increase. Each year during Thanksgiving weekend, shoppers are turning to their computers and cell phones more and more to find the perfect gift or the best deal. More online shopping means more packages to ship, and more paper to coat.
Paper coating demand is expected to rise to more than 3.2 million tons of material by 2020 from 2.4 million tons of material in 2014, according to a new report from Smithers Pira, a leading expert in packaging, paper and print market trends worldwide.
This increase in demand is partially due to the need for more packaging per year, including packaging for items purchased online.
With more and more retail customers choosing to stay home to shop, packaging needs are on the rise. For example, Thanksgiving weekend in 2015 saw $11 billion in online sales from Thanksgiving Day through Cyber Monday.
Adobe Systems’ market research also noted Cyber Monday hit a record high at $3.07 billion in sales this past year. Evidently, shipping and packaging are on the rise, which correlates to paper coating increases, as well.
In general, more than 30 percent of paper-based packaging has some kind of coating as a barrier or as another function, and this statistic includes the 100 percent of liquid packaging requiring a coating. These paper coatings can be a compound or polymer to impart weight, gloss, or lower ink absorbency on the paper surface.
As one of the most advanced paper coating companies in the industry, we plan to continue providing the best service and products in coatings. Three coaters help us support industry needs–two that are equipped with flotation dryers and one that is equipped with hot melt gravure coating.
Our wide web coaters can work with paper rolls as large as 62 inches wide. These same coaters are specially designed for low or high coating weights. Methods include the following:
Our Hot Melt Coater and Laminator can use an offset gravure coating method. Its thermoplastic melting point is at 300 degrees Fahrenheit, or 149 degrees Celsius. Overall, our equipment is capable of laminating multiple layers of similar or different substrates.
Specific food-grade paper and our FDA-approved coating surfaces can be produced to the most specific of formats and requests for various packaging coating purposes.

As more brands seek to adopt environmentally conscious practices, the demand for eco friendly packaging increases. Poly replacement coatings for food packaging have historically been more expensive than standard poly materials.
The team at Sierra Coating aims to bridge the gap between cost and performance. Though the cost of poly replacements, polyvinyl chloride (PVC) replacements, and other eco friendly coatings are steadily decreasing, we’re working to hasten that process. Chemical experts at Sierra are equipped with the knowledge and experience to provide a wide range of eco friendly solutions by sourcing coatings and substrates to replace plastic in packaging.
Over the years, our team has orchestrated and contributed to a number of environmentally friendly packaging development projects, working with the nation’s leading chemical companies to deliver eco friendly coating solutions.
RELATED: Taking the Eco-Friendly Packaging Leap
Driven largely by the desires of consumers and major retailers, the packaging industry has been moving toward sustainable options. Gaining momentum over the years, eco friendly efforts increased dramatically when the largest retailer in the world created an environmental impact scorecard for product packaging.
There a variety of ways to create an eco friendly package. Below are some common methods:
A recyclable package can be reprocessed back into the work stream. Plastics are generally all recyclable, but several limiting factors must be taken into consideration. For example, not every county or municipality has the proper recycling laws or infrastructure to support certain types of plastic recycling. And when they do, recycling can be difficult to enforce.
Municipalities also have varying restrictions on what is recyclable – some municipalities won’t accept plastics that are soiled in any way, which food packaging almost always is; some recycle limited types of plastics; and some restrict what can be recycled based on their size or shape. These restrictions and challenges make paper-based packages with water-based, food-safe coatings attractive alternatives.
Sierra Coating Technologies is proud to nurture a culture of innovation, which acts as the foundation of our business. Interested in learning how to make your packaging eco friendly? Contact our product experts today.
