The food industry nowadays is not only eyeing for the quality of their snacks and desserts products but also for its packaging use to comply with the strict standards set by environmental organizations and to be wary of consumers who are environmentally conscious. There are various materials used for packaging nowadays, but since food is prone to spoilage, it needs special types of packaging to preserve its quality and freshness.
Usually, snack products use flexible packaging such as board tubs, bio-sourced materials, and folding cartons.
Metalized Polypropylene Films
Metalized films are known to be used in applications such as insulation and electronics, but they are also common packaging materials for food. These films serve as protective barrier to preserve the snack’s flavor, and these are also useful as susceptors for heating food in microwave oven, such as microwavable popcorn bag. Some food items are packaged using metalized films for aesthetic purposes because it sparkles when compared to other snacks that use polymer films or printed paper.
These are rigid packaging alternatives that can be crushed or can be used in a variety of applications including its board substrates. Other snack manufacturers are integrating board elements with other packaging materials such as board trays and flow wrappers. These materials are convenient too because it can be pulped down and easy to dispose after consuming the contents.
These eco-friendly options make use of compostable bags that are made from wood pulp and can decompose in industrial composting facilities after three months. These alternatives are just ideal for food packaging because of its low permeability to bacteria, oil, grease, air and water.
Another food types that need careful packaging to maintain its taste and freshness are the desserts. Nowadays, there are packaging forms that adhere to the environmental standards without compromising the way of protecting desserts.
Expanded Polystyrene (EPS)
EPS ice boxes help ensure that desserts, sorbets for instance, are maintained at the right temperature when they are delivered from the check out to the consumer. These packaging materials help preserve and protect the quality of the desserts and do not contain additives that can make cold desserts melt quickly. A special form of EPS has high air content, and the box itself can be broken down, incinerated, or recycled.
Recycled Polyethylene Terephtalate (rPET) Plastic
Ice desserts can maintain its freshness with the aid of specially-designed cup that has no Bisphenol-A (BPA) and phthalates. The outside of the cup is mainly made of recycled polyethylene terephtalate (rPET) plastic, which can be used as packaging. The rPet levels vary depending on the supply. On the other hand, the inside of the cup is made of Cradle to Cradle (C2C)-certified plastic. The certification obliges producers to eradicate wastes and utilize eco- friendly production methods instead.
So these are just some of the sustainable materials that can further preserve the freshness, quality, and tastes of your snacks and desserts wherever and whenever you want to eat them. Regardless of how sustainable the packaging is, however, just make sure to check the expiration labels before consuming to fully enjoy your sweet treats.
