Listing of Films
Low-Density Polyethylene (LDPE)
Inexpensive, have high clarity, heat seal-ability, and are often used to package fresh produce, frozen foods, and goods.
The most flexible of plastic sheeting. It is stronger and more flexible than low-density films. These films are extra durable and can be used for strong films meant to absorb impact without worrying about puncturing or tearing. Stretch films, bundling films for water bottles, and stock poly bags also rely on LDPE and LLDPE. These films can be customized to add company artwork for a more branded look.
Linear Low-Density Polyethylene (LLDPE)
High Density Polyethylene (HDPE)
Found in similar applications as low-density. One key difference is that high-density films are more rigid and stiffer than average polyethylene films. HDPE protects products from moisture barrier properties and is resistant to grease and oil. HDPE films are often used in boxes to preserve the contents, including cereals and cake mixes.
Low cost and often used to package baked goods, confectionery items and can manufacture stand-up flexible pouches. The film has high gloss, optics, and has an excellent heat-sealing performance. CPP has higher tear and impact resistance and is good for cold temperatures.
Cast Polypropylene (CPP)
Films provide an extra layer of protection because of their design. Two or more flexible packaging webs are joined using a bonding agent. The webs are made of films, papers, or foil. When the adhesive is applied to the substrate, or base material, and is pressed together, the result is a two-layer laminate. Common applications include ready-to-eat food products, medical, cosmetics, and insulation.
Have a clear appearance and is a printable thermoplastic. Nylon films have a relatively high melting point, excellent strength and toughness, and good oxygen barrier properties. It does not absorb grease, oil, or acidic food, which makes it ideal for conventional cooking and microwavable applications. It has higher tensile strength and is harder to stretch compared to LLDPE and LLPE films. It is used for important food applications such as processed meats, smoked fish, cheese, and dairy products.
Biaxially Orientated Polypropylene
Low-cost thermoplastic of high clarity, high gloss, and sturdy tensile strength. It is a much better alternative to cellophane, waxed paper, and aluminum foil because of its strength, stiffness and it is harder to stretch. BOPP has good vapor and gas barriers. It is ideal for hard candies, chocolates, and wrapping flowers.
A thermoplastic that has high tensile strength, can maintain its original dimensions when subjected to a wide range of temperature changes, along with superior UV resistance and good optical clarity. It’s a very good film for high-quality printing and lamination, as well. When PET films are laminated with metal foil, it increases the film’s oxygen-water barrier and blocks out UV rays. Metallized PET films have a longer shelf life and provide extra protection for food items that require restricted visibility. Other key uses include medical packaging, protective coatings, plastic wrap, tape backing, and plastic cards. PET is also used as an aroma film for coffee and tobacco.
Polyethylene Terephthalate (PET)
Barrier films are increasing in popularity in the food industry. The film acts as a seal to protect contents from outside conditions that can severely affect the quality of the product and ruin the original conditions inside the bag. Barrier films are specially designed for resistance from the aroma, flavors, gasses, and solvents.
The films are manufactured with multiple layers and offer various degrees of permeability. Barrier films are available in Autobag Bags-On-A-Roll and SidePouch Bags-In-A-Box configurations.
The high strength of the polybag material resists tears and punctures and provides unique barrier properties.
For specialty custom barrier films, Pyramid Packaging will work with customers to help engineer films for a variety of frozen foods, pet foods, waterproof, greaseproof, odor-resistant, and military bagging applications. Our specialists will formulate solutions to match your application’s needs.
