Features of Functional Film

Multi Purpose
Our functional film packaging is BRC approved for food contact applications. They can be used in packaging applications for a variety of materials, including fresh produce, meat snacks, refrigerated poultry, as well as pharmaceuticals and personal care products.

Anti-fog Surface
Produced through co-extrusion thermoforming technology and utilizing a variety of anti-fog technologies, these packaging films are able to provide a clear window for products that are typically refrigerated or contain grease, maintaining a clean, dry appearance.

Highly Sealed
The packaging bags made of them have a uniform composite lining and a highly airtight plastic inner seal, which can isolate gas, liquid, and sunlight from entering to prevent oxidation activities and food decay.

Slim Design
These functional film packaging have optimized structures, add complex patterns and font designs through flexo and gravure printing, and have extremely thin thicknesses, with the thinnest being 40 microns.
Food and Beverage
Food and beverage flexible packaging, both retail and institutional, is said to account for a near 60 percent of all flexible packaging applications, with some market studies claiming a market share as high as 80 percent. It largely depends on exactly what a specific study includes. Does it include shrink sleeves or not? Does it include industrial applications?
In particular, the rising demand for snack and convenience foods in small or single size portions, increased spending on bakery and cereal bars, short-run ready meals and coffee or hot chocolate sticks and pouches, dehydrated and dry foods.
Stand-up gusseted pouches and pillow pouches are widely used as flexible packaging products in the food sector. Pillow pouches have also witnessed high gains due to their increasing usage in the food, beverages and dairy industries.
Health, Beauty and Personal Care
The healthcare, cosmetics, toiletries and personal care markets have long provided a wealth of opportunities for the label converter. Now, they also offer the opportunity to diversify into the production of high quality sachets, pouches and packs for many different ‒ often shorter run lengths of multiple versions and variations ‒ types of flexible packaging for the whole health and personal care market that includes toiletries, hygiene, shampoo, liquid soaps, creams, lotions, gels, cosmetics products, beauty products, wipes and packs.
Pharmaceutical, Nutritional, Nutraceutical, Veterinary and Medical
A study of flexible packaging in Europe identified pet food as being the best performing flexible packaging category. Pouches for pet foods and pet products are identified as the fastest-growing segment of the animal care market, due to them being easy to carry, store and re-seal to ensure freshness.
Retail Non-food, Home and Garden
Depending on the particular market study viewed, the whole non-food, home, DIY and garden sector accounts for up to 10 percent of the flexible packaging market, with products that include household items, laundry detergents, soaps, bath salts, under-the-sink packs, paints, pastes and plaster, lawn care, fertilizer, pesticides, grass seed, compost and bark.
Benefits of Functional Film
Functional film is touted for its ability to be customized based on the specifics of the product being packaged. Regardless of shape, size or visual needs, this solution gives you the flexibility to tailor your packaging according to your unique specs and market objectives. This is a real competitive advantage.
To protect and secure products for retail and shipping environments, there are three main types of films: polyvinyl chloride, polyolefin and polyethylene. Each one features different capabilities and characteristics that make them suitable for specific applications, or they can be combined to create multilayer films with distinct barrier properties for better protection or longer shelf life. Functional film can also add a form of tamper-resistance to packaged goods if necessary.
The customization element extends to visual properties as well, including clarity, glossiness, and printability. It allows you to really showcase your product and brand in an eye-catching way. Some formulations of shrink film are ideal for packaging meats or frozen foods, as they enforce barriers to reduce fog or moisture-vapor transmission. You have the ability to print high-quality graphics in an array of colors and designs to wrap your product in creativity and style or to include important information right on the package.
Versatility in a packaging solution is key. With the variety of options in flexible packaging, you can create a package that stands up, hangs from a peg display or sits on a shelf. In other words, the packaging works for the product rather than the other way around.
Flexible packaging films have been designed with numerous product requirements and realities in mind. There are options that prioritize durability and resistance to tearing, safe distribution and storage, freshness and food safety, and protection from environmental elements like temperature, light, moisture, and gas. Functional film helps to increase the shelf life of perishable items and can conceal the smells of the packaging’s contents.
Because Functional film can be tailored to the specific size of your product, there’s no need to use more materials than absolutely necessary. It can conform to your goods and render a higher product-to-package ratio, which has the potential to reduce your manufacturing costs. Dynamic utilization of flexible packaging films helps to simplify your packaging systems, eliminating the cost of labeling or capping, for example.
With the use of high-quality films, you can often phase out the need, and corresponding cost, for added packaging elements like corrugated trays. Plus, the expense of implementing flexible packaging film, from materials to production costs, is significantly lower than that of plastic or glass containers. Since flexible packaging is lightweight, it’s more affordable to ship domestically and internationally.While it may seem strange, adding more layers to your flexible packaging design can help improve production costs and functionality, as doing so allows for more precise control of the layers and fewer limitations. This minimizes the need for complex engineering.
Flexible packaging can be designed to include features like zip locks, spouts, and seals that can be resealed after opening. As consumers increasingly seek options that deliver greater convenience, this benefit supports the opportunity to attract more sales. It further advances market appeal to customers who take an interest in finding new uses from what they already have in their homes.
Material Types of Functional Film
Polyethylene Film
The most popular nylon and packaging plastics are made from this recyclable material. Polyethylene is a plastic film made from ethylene, a hydrocarbon mainly obtained from natural gas or oil. The terms “plastic sheet”, “polyethylene sheet”, or “poly-film” are often used as synonyms for polyethylene film. The term polyethylene is abbreviated as “PE”. There are different types of polyethylene film, the most popular of which are:
●Low-density polyethylene (LDPE)
●High-density polyethylene (HDPE)
●Linear Low-Density Polyethylene (LLDPE)
PE film can be purchased in different colours or transparent. In addition, there are different thicknesses.
Polyolefin Film (PO)
Polyolefin is a durable, widely used, FDA-approved, food-safe plastic. The main feature of this material is its strength. Polyolefin film (POF) is thin yet strong, with high puncture resistance and sealing strength. The structure of this film is such that irregularly shaped goods can be packaged without any problems using it.
POF is 100% recyclable and offers impressive transparency, making products stand out more. Manufacturing companies may add tiny holes to the film during manufacture to give it exceptional flexibility. Applications of polyolefin film are generally in the following industries, although any product with small dimensions can be well packaged with it.
When producing this film, no harmful fumes are emitted during processing, and it is environmentally friendly. On the other hand, it is entirely recyclable, so the production of new products from oil sources is reduced. But this product has other advantages
Polypropylene Film (PP)
Polypropylene (PP) is a thermoplastic “additive polymer” made from a combination of propylene monomers. This material has a high melting point, which makes it suitable for hot liquids. It is also perfect for specific applications that require good chemical resistance. PP is mainly used directly in the packaging industry and is one of the most widely used packaging films. Of course, this material is also used in electrical equipment production, household appliances and automotive industries.
Polypropylene has a variety of uses, such as packaging consumer products, making plastic parts for the automotive industry, and producing special devices. Of course, polypropylene film is often used as the outer layer in multi-layer packagings, such as bags with polyethylene. Yogurt containers, take-out foods, medicine bottles, etc., are other items made of PP.
Polyvinyl Chloride or PVC Film
As PVC is reliable and lightweight, it helps the packaging maintain the integrity of the products. Of course, compared to other films, this film has a fragile structure. Also, its manufacturing process is associated with releasing toxic fumes, which is harmful to the workforce, and its factories must have proper ventilation.
PVC is a thin thermoplastic film available in various shapes and coatings. Depending on the requirements and constraints of the industry, However, since it can release harmful chemicals when melted or burned, appropriate precautions should be taken to reduce the risk of adverse health effects if used in industries where the material is used in operations involving flame or high temperatures.
Low-Density Polyethylene Film (LDPE)
It is a type of polyethylene film, but due to its importance and wide application, we examine it separately. This material changes its shape when exposed to heat and can take a new shape many times without losing its structure and strength. LDPE is a semi-crystalline thermoplastic with a nearly compact molecular structure. This film has many advantages, but what makes it popular is its soft, flexible nature and high adaptability for use in making different materials.
The primary material of the film, LDPE, has been used in producing other materials, such as stretch film and nylon shrink. This film is easily recyclable, thus significantly reducing our environmental concerns.
Thin Plastic CPP Film
The word CPP is abbreviated (Cast Unoriented Polypropylene) and is a plastic derived from polypropylene. CPP film is suitable for traditional and modern packaging applications, from side-seal pouches to stand-up pouches for textile and food packaging and document protection. CPP plastic has the advantages of low moisture permeability, good heat resistance, thermal sealing, etc. It can make moisture-proof, heat-resistant, non-toxic and odourless packaging.
OPP Packaging Film
OPP stands for oriented polypropylene and is a type of propylene film. OPP is a flexible, colourless, odourless, tasteless, non-toxic packaging material with high tensile strength, impact strength and transparency. The production method of OPP film is that the molten polypropylene polymer is first made into a thick sheet or film through a long and narrow series. Then it is placed in a unique stretching device simultaneously or step by step at a specific temperature and speed. This film is made by stretching in two vertical directions (longitudinal and transverse) after cooling or appropriate heat treatment or special processing.
Packaging material is an essential part of building a successful product and there are many important factors to consider when choosing the material that works best for your product’s needs.
Product Compatibility
Does the packaging material keep your product protected during transport, storage, and on store shelves? Are specific barrier properties needed to prevent moisture or oxygen from affecting the product? Does your product need to be in dark-colored material to protect it from sun and light exposure? Understanding your product’s unique requirements to maximize its shelf life is key to identifying the right packaging material to pair with your product. What packaging size are you looking for? Choosing the right size packaging can also affect your material options. More packaging material options are available for smaller consumer products, but for larger sized containers for bulk products, some materials are not as commonly available due to factors such as fragility or manufacturing capability.
Marketing
Once your material options have been identified, you can take your marketing goals into consideration to further narrow down your packaging material choices. A common marketing goal for the container is how you want your customer to view your products. Do you want clear packaging for the product to be clearly visible through the packaging material? Do you have sustainability goals that would lead you to choose a sustainable material?
Cost
Shipping is one area that can drive your cost up. For example, if your product is packaged in glass - a heavy and breakable material - then you’ll need to factor in the additional cost of weight for shipping as well as taking into consideration items that may be damaged due to breakage. You can limit breakage by providing extra protective wrap to keep the product safe during transport, but this too is an additional cost to consider. Aluminum is another material that can be easily damaged and dented during transport if not well-protected. All materials have advantages and disadvantages. It’s vital to make sure you thoroughly test your product with the container made from your packaging material choice to calculate base packaging costs, but also be aware of external costs such as shipping.
Convenience & Availability
Having a trusted packaging supplier to help you navigate the vast world of packaging can help minimize costs by identifying the best material to fit your product’s needs. Since suppliers work with companies from a spectrum of industries, they can save you hours of research by identifying the material that will best suit your product with their experience serving previous customers in your industry. In addition to a packaging supplier’s knowledge, specifically with packaging distributors, distributors may already stock container styles immediately available for purchase in the material you’re interested in.
