Metalized to Perfection: High Barrier CPP Films

Cast Polypropylene Films, commonly known as CPP films are probably the most sought-after packaging solution, thanks to its versatility, flexibility, cost and robustness. Available in two types, General and Metalized high barrier films, CPP films are a one-stop solution not just for the food packaging and agricultural industries, but also for the healthcare and pharmaceutical industries. In this blog, we will discuss the benefits of metalized high barrier CPP films. Known for its resistance to tear and its robustness, metalized high barrier CPP films are widely used for food packaging needs.

Let’s take a look at some of the top features of this variant –

1. High oxygen barrier – Oxygen is the biggest contributor to food spoilage. This metalized CPP film blocks oxygen and helps to maintain the shelf life of the product. The films offer an OTR of <30cc/m2/day.
2. High moisture vapour barrier – These metalized CPP films also provide excellent barriers for moisture and humidity.The film offers an MVTR of <0.3g/m2/day
3. High hot tack and low SIT – Hot tack force refers to the peel force of the sealing area when it is not completely cooled down.The hot tack is higher than 600gf/inch for a temperature range of 100 – 140̊C, and a low seal initiation temperature, thus making it easier to laminate the film on all kinds of machines.
4. High heat seal strength – At more than 2.3kg/inch, the heat seal strength offered by metalized high barrier CPP films is excellent.
5. Seal initiation – These films offer a low and wide seal initiation temperature range (90 – 105̊C). The wide thickness range rests between 20 – 30μm.
6. Exceptional machinability – Metalized high barrier CPP films are easy to process and offer good printability.
