Types of PET Films used in Flexible Packaging
India's rapid progress has spawned a number of industrial revolutions, each of which moves us closer to a more comfortable tomorrow. Perhaps nowhere is this more evident than in the packaging sector. As a result of flexible packaging's launch and subsequent success, the market is expanding rapidly. With the meteoric rise of e-commerce, the future of the flexible packaging sector is bright.
Let's start at the beginning: what exactly is flexible packaging, for the benefit of those who may be unfamiliar with the term? Flexible packaging refers to any kind of packaging that may bend or flex when it is filled or closed. It's form is easily adaptable to new circumstances. Products for both consumers and businesses benefit from this type of packaging. Pouches, sleeves, bags, tubes, shrink films, as well as carded packaging are all examples of common types of packaging.
The incredible variety of options available is one of the many exciting aspects of flexible packaging. Different items require different kinds of protection from the elements or aesthetic enhancement from various flexible packaging materials. There are many varieties, each with its own set of qualities and applications based on the product being packaged. GLS Group one of the top-ranking PET packaging film companies in India has listed the 7 types of PET films used in flexible packaging:
Primary Flexible Packaging Film Types: 1. Linear Low-density Polyethylene (LLDPE):LLDPE tops the list because it is the most flexible plastic sheeting film option. It's simply a more advanced kind of LDPE, with the same outstanding potential to absorb force without puncturing or ripping. Besides their malleability, these films are notable for their longevity and resilience to chemicals.
Plastic bags, pouches, wraps, covers, toys, pipes, lids, containers, buckets, as well as the like are all examples of ubiquitous plastic products. Furthermore, they are frequently utilised as pond liners, carpet backing, cable jackets, geomembranes, and mostly flexible tubing.
2. Low-density Polythene (LDPE):LDPE, which has been used as a packaging film since its introduction in 1933, is a very malleable and lightweight plastic. In its purest form, it is a thermoplastic derived from the ethylene monomer. These films excel in areas where durability, flexibility, chemical and impact resistance, as well as corrosion resistance are required, such as at low temperatures.
More importantly, they are simple to produce by employing a high-pressure technique based on free radical polymerization. They are high in-demand option for food packaging since they guarantee that products are safe to eat and can be recycled. Can tops, shopping bags, and various films as well as plastic wraps are all made using LDPE. In addition, it performs admirably in processes like extrusion, blowing, and injection.
3. Bi-axially-orientated Polypropylene Polymer (BOPP):Due to their transparency, clarity, and unrivalled resistance to moisture, these films are the clear favourite when it comes to commercial packaging. FOIL is commonly used to supplement BOPP. Its performance is greatly enhanced as a result of this. If you are looking for the most popular PET Films company in India, GLS Group is the right place for you that can fulfil all of you PET film needs.
BOPP films are cutting-edge alternatives that are widely employed in the production of clear wraps and a variety of snack food packaging nowadays. Pesticide and toiletry product packaging are two more frequent examples. These films facilitate recycling, allowing businesses to keep their word on environmental responsibility.
4. Bi-axially-oriented Polyethylene (BOPE):If you need to ship items that are extremely rigid in their packing, BOPE is your best bet. These films are superior to others in a number of ways, including their capacity to withstand punctures and tears, their transparency, their longevity, their resistance to moisture, and their high gloss. The expense to make these movies is little.
BOPE films are cutting-edge options that are widely implemented today in applications including grocery bags, medicinal containers, and even liquid and spice containers. These films' recyclability aids businesses in keeping their green promises to customers. Moreover, despite the numerous benefits, these films are quite cheap.
5. Biaxially-oriented Polyethylene Terephthalate (BOPET):White or clear BOPET films were created for the first time in the 1950s. They're constructed with PET that's been stretched (PET). Their popularity stems from the fact that they are see-through, reflective, chemically and dimensionally stable, inert at high temperatures, provide a barrier to gases and aromas, and are electrically insulating.
It's also commonly utilised as a lamination surface film. Laminating food products in BOPET foil helps prevent oxidation, which keeps the food's natural odours and flavours intact and extends its shelf life. Coffee in foil packages and snack food pouches are two examples. Modern Pop-Tarts packaged in silver BOPET are a humorous illustration of this trend.
6. Biaxially-oriented Polyamide (BOPA):BOPA shares many of the same desirable qualities as BOPET, including remarkable tensile strength, durability, scent barrier, and puncture resistance. Transparency, though, is what people value most about it. It effectively blocks the passage of oxygen and some chemicals.
If you're looking for quality films manufactured by one of the most preferred PET Films companies in India
- GLS Group is a trusted name inthe industry. If you wish to use PET films for packaging frozen vegetables, foods, technological devices, medical equipment, aquatic products, etc., then look no further than GLS Group. In addition, it can be used for food and even some medicines.
Laminated film are often seen being widely used for food packaging; it's common for flavoured drinks, condiments like sauce, and preserved foods and powders to all come in laminated packaging.
Aluminum or metalized films are typically supported by a polymer film or paper in these multi-layer structures. They are constructed so that they effectively block the passage of odours and aromas.
