Flexible Packaging Films

flexiblepackagingfilmsFlexible packaging films are used to package, preserve and protect a variety of items such as fresh foods, dry goods, pharmaceutical and consumer products. The films are used to make poly bags/pouches, stretch wrap, shrink wrap, bubble wrap and void fill supplies. Flexible packaging supplies provide several advantages because they are lightweight resulting in lower shipping cost, moisture resistant, and require less storage space over their rigid packaging counterparts, an are inexpensive to produce.

flexible packaging filmsFlexible films start off as plastic pellets. Most plastic packaging films are blown films. Plastic pellets are fed into an extruder where they are melted and ejected through a circular blown film die. The melted plastic forms a continuous tube, which is inflated and cooled. Plastic film rolls can be printed & laminated to optimize graphics. They have superior barrier properties and excellent sealing characteristics. can be placed on different types of packaging machinery in order to maximize productivity.

There are many different types of flexible films available. Deciding on which type depends on your application. The most common type of films are polyethylene, low-density polyethylene, high-density polyethylene, polypropylene, polyolefin, PVC, and polyester. Polyethylene shrink films are often used to wrap bottled water, canned goods and other heavy objects. It’s ideal for wrapping large & bulky items during transit. These films are so strong they can replace corrugated boxes. Polypropylene is a general-purpose shrink film often used to wrap retail items. It shrinks at low temperatures while providing durable seals. Polyolefin is a clear film that shrinks evenly in all directions. This film allows scents to permeate it. Since it requires high temperatures to shrink the film, it’s often applied with a shrink-wrap machine, which increases productivity and allows items to be bundled together. Polyolefin films are used to wrap retail items, food/snacks and literature. PVC shrink films have high strength with good clarity and gloss. It’s used to package software items such and CDs, DVDs & Blue-ray discs but also used to wrap books, toys & food items. Polyester (PET) is a tough, durable plastic, which is used or flexible pouches, and barrier films.

Food Metal Detectors

Food-Metal-DetectorsFood metal detectors are used for consumer protection. The consequences for a food related packaging company that is not using metal detectors can include lawsuits, recalls and hurt their brand image. Parts of the food processing and packaging equipment like nuts, bolts or metal shavings can possibly fall off an accidentally be packaged with the food items. Metal particles that enter the product during the production process can also cause serious injuries. Food X-Ray machines metal detectors will automatically detect & reject contaminated product from the production line. Loma food x-ray detectors will provide effective protection against metal as well as non-metal contaminants.

Textile Packaging Equipment

Autobag's new Ergocon Textile Packaging System is engineered specifically for high speed packaging of industrial laundered applications and textile rental services. The laundry packaging system uses an automatic feeder, fully integrated with the Autobag® AB 255 wide bagger, to inspect and package up to 7,000 towels per hour.

The inspection and packaging operation begins by loading the bulk feed bin with clean towels or other industrial laundered items. Loading can be done while the system is operating.

Items are automatically fed from the bin to the pick conveyor for separation, and are then conveyed to the inspection area. After inspection, towels continue down the conveyor, pass through a counting eye, and are automatically delivered to an open bag at the AB 255.


This commercial laundry equipment sets the pace of production.  Speeds are adjustable to run slower for items requiring tighter inspection or faster to achieve high production rates.

The user-friendly control panel allows storage and recall of up to 14 jobs with load building capabilities, real time productivity data, onboard diagnostics, and more. Optional features include a performance indicating light stack, laser level control system, reject count system, and an extended 71” discharge conveyor. When used with genuine Autobag pre-opened bags, the Autobag Ergocon Textile Packaging System offers high-quality, reliability and flexibility for the commercial laundry industry.

Why Use Anti-Static Shielding Bags

anti-static poly bagsAnti-static shielding bags are used to store, transport and protect electronic components and printed circuitry boards. The bags will protect electronic items from damage when electrostatic discharge occurs. Static electricity occurs more often when there are low amounts of moisture in the air. Anti-static bags have a thin microscopic layer of water molecules at the film's surface which reduces the chances of a discharge from taking place. Additionally, controlling the humidity level of a room will reduce static electricity. Anti-static bags are commonly made from low density polyethylene (PE) or polyethylene terephthalate (PET) and have a pink or silver metalized color.


To create the anti-static effect, the bags are slightly conductive, which creates a Faraday Cage around bagged item which avoids any discharges from being deposited onto the item. Anti-static bags will dissipate static electricity so it cannot create electrostatic discharge (ESD) whereas a static shielding bag blocks the ESD. Pyramid Packaging is a supplier of the following types anti-static bags:

  • anti-static reclosable/ziplock bags

  • anti-static flat poly bags

  • anti-static tubing

  • conductive flat bags

  • conductive bags reclosable/ziplock

  • conductive tubing

  • static shielding bags

  • cushioned static shielding bags

  • reclosable/ziplock

  • available in clear, pink, various sizes and thicknesses

Choosing the Right Poly Bag

Poly-BagsChoosing the right poly bag (film) for your packaging application can be a confusing process. If you're not familiar with packaging films, you may think they are basically all the same but nothing could further from the truth. Poly bags come in different styles, materials, thicknesses, blends, barrier properties and available in loose pack and rolls.

Bag Types
Poly bags are also known as poly and plastic bags. They are commonly used of packaging applications. Poly is short for polyethylene which is the material they are made from. They are used for bagging foods, produce, dry goods, magazines, chemicals, and also for storage. The most popular types of poly bags are layflat, gusseted, and zip lock.

Lay flat plastic bags work great for packaging products and protecting them from dust, debris and fingerprints. These bags provide a barrier of protection during shipping and storage. As the name implies, the bag lays flat and does not expand beyond the natural elasticity of the plastic.

Gusset poly bags have sides that expand. The bags are made from polyethylene and come in various thicknesses (1 mil to 4 mil) and sizes for various packaging applications. They are used to package industrial, hardware, food, and healthcare related items. Gusset bags are available in loose pack and rolls. The bags are an ideal packaging solution for irregular shaped items. Since the sides expand, they will conform to the shape of your box product.

Zip lock bags provide secure locking zipper which provides an excellent way to keep out foreign substances that may damage a product. Due to its reclosable feature, it is easily reusable and is great way for keeping out moisture, and dust.

Poly films also come in tubing and sheeting which allows you to customize its lengths.

Bag Materials
Poly bags come in an array of materials that including but not limited to LDPE, HDPE, PP and PET. Variables like the films clarity, oxygen and moisture barrier rates will help decide on which film type is best for your packaging application.

Linear Low Density Polyethylene (LDPE) packaging films are inexpensive, have good clarity and often are used to package fresh produce, frozen foods and baked goods. Artwork can be added to give the product a branded and customized look.

High Density Polyethylene (HDPE) packaging films are found in many of the same applications as LDPE and LLDPE. It is stiffer and more rigid than other PE films. HDPE has good moisture barrier properties and is resistant to grease and oils. HDPE is often used inside a box to preserve its contents such as cereal bags or cake mixes.

Polypropylene (PP) films are soft, clear, have good moisture barriers and high oxygen transfer rates. PP films used as plastic food bags in bakeries, and food markets. These films are similar but less flexible than LDPE films.

Polyethylene Terephthalate (PET) films are durable, heat resistant films with
very good oxygen barrier properties. When PET films are laminated with metal foil (MET PET), it will increase the film’s oxygen-water barrier and block out UV rays. Metallized films for flexible packaging are essential when the product requires extra protection to ensure a longer shelf life. MET PET films provide protective properties for food items requiring restricted visibility.
