All Curiosities About Bakery Product Packaging

Materials such as PE (Polyethylene), OPP (Oriented Polypropylene) and CPP (Cast Polypropylene) are widely used in bakery product packaging. These materials are preferred for different purposes in the packaging industry because they have different properties.

1. PE (Polyethylene): PE is a popular packaging material due to its properties such as flexibility, durability and water resistance. It can be produced in different densities and is often used in products such as plastic bags, cling film and food packaging. PE packaging is usually classified as low density (LDPE) or high density (HDPE). LDPE is more flexible, while HDPE is more rigid and durable.

2. OPP (Oriented Polypropylene): OPP is a transparent type of plastic and has a surface suitable for printing. It is therefore preferred for clear display of graphics and text on packaging. OPP film is usually used as transparent or opaque. It is commonly used for packaging products such as dried foods, snacks, biscuits and chocolate.

3. CPP (Cast Polypropylene): CPP is a derivative of polypropylene produced by the cast method. It is more flexible than OPP. CPP can give products a longer shelf life and better protect the contents against external factors. CPP is often used in the packaging of products such as frozen foods, bakery products, coffee and nuts.

The choice of these materials is based on factors such as the characteristics of the product, the protection needs of the packaging, the production and printing processes. In packaging design, it is important to pay attention to the type of product, transportation conditions and the experience offered to the consumer.
