Recently there has been a shift in consumer consciousness towards using more sustainable materials and films. Consumer perspective is shifting. The market for zero waste and sustainable materials expand. For instance, Green Business Bureau (GBB) member ‘ International Inc’s’ entire business model leverages this market expansion. Business’s are implementing many packaging changes to become sustainable.
The first approach adopted by companies is to switch over from laminated multilayer materials to mono materials. This can be done by using a multi-layered material made up of the same characteristics. On some occasions having no less than 3-5% of any potential additive.
Another approach is to look for reduction in film usage. This can be achieved by reducing the micron or by reducing the width and crimps. When looking at film we need to examine the expected throughput the presentation and characteristics of the product and the required space for marketing. Once we have set these parameters and weighed the importance of each factor for the end consumer, we can then look to recommend the correct film solutions for their application.
The final approach is finding out the specifics around machine design to reduce film wastage. For this approach some manufactures such embellish their ability to do this. However, this can be achieved by using a fixed folding box and reduced crimps on your packaging machine. Sealing systems such as ultrasonic sealing or impulse sealing allow reduce the sealing area and therefore use less plastic than traditional approaches. We can consult on any application and advise as required to each customers specification.
The second approach we have seen is in the form of customers switching from plastic based materials to compostable materials. We have seen customers switch over to PLA based and fibre-based films but more recently there has been an ever greater request to switch over to paper-based films. There are two different types of paper-based material. Paper with a PE laminate on the inside to allow for the sealing of the packs or their is also the availability to use paper with PE spray. This product is often advertised as 100% natural material with an eco-friendly plant-based coating. This is because we can use sugar cane to make poly ethanol which can then be used for the spray layer. Poly ethanol and polyethylene have the same chemical structure making this an ideal substitute.
MAP is a packaging method that involves altering the atmosphere within the package to slow down the spoilage of the product. This is achieved by removing oxygen from the packaging and replacing it with a mixture of gases such as nitrogen, carbon dioxide, or argon. By doing so, the growth of microorganisms that cause spoilage is slowed, and the shelf life of the product is extended.
MAP packaging extends the shelf life of products. This results in fewer emissions generated by the production, transportation, and disposal of the wasted food.
MAP packaging can reduce the need for refrigeration. Refrigeration is a significant source of energy consumption. With MAP packaging methods and materials, products can be stored at room temperature, reducing the need for refrigeration.
MAP packaging can help reduce the use of preservatives. Preservatives can have negative impacts on the environment and human health. MAP packaging extends shelf life significantly, reducing reliance on preservatives. This helps protect the environment and promote healthier food options.
