The choice of the correct substrate for the production of a flexible packaging mainly takes into account its cost / benefit ratio as a function of its properties and visual appeal.
Flexible packaging developed the unique needs of the products to be packaged. Due to their surface treatment and additives, they have facilities in print processing, lamination, sealing ability, sliding and performance in packaging machines. They are designed to protect, conserve and maintain the organoleptic quality of packaged products, extending their shelf life.
BOPP (bi-oriented polypropylene) stands out for its great features such as: glossy, transparent, opaque, matte or metallic appearance, providing strong visual appeal in supermarket gondolas and other points of sale. The material offers excellent protection and integrity for packaged products such as gas, oxygen and moisture barriers. BOPP films are extremely versatile and efficient when used in various types of packaging, especially in contact with food and thus must be produced under strict hygiene and cleaning conditions suitable for human health.
PP (polypropylene) is recommended as a fat barrier, has good thermal stability, greater sensitivity to UV light and oxidizing agents, and is more easily degraded. Good impact resistance at room temperature, excellent transparency, low water vapor permeability and very low electrical conductivity. PP films are extremely versatile and efficient when used in various types of packaging, especially in contact with food and, therefore, must be produced under strict hygiene and cleaning conditions appropriate to human health.
Suitable for products that require barrier against fat such as: snacks, peanuts, flours, cereals, sweets in seasonings, proteins, and also non-food products such as: bags for clothes, etc.
Supplied in parts (bags) or technical reels for automatic packaging on machines with flow pack system, and can be printed in up to 8 colors.
