Achieve Sustainability and Cost Savings with High-Quality Drum Liners

Drum liners

When it comes to problems with drums, liners can hold the line.

Steel and plastic drums, from 12 to 55 gallons, have long been a popular way to ship bulk food ingredients. They are sturdy and relatively easy to store and handle. However, they also present certain challenges. They can be hard to evacuate completely; cleaning and reconditioning them is labor-intensive; and products that are abrasive, high in acid, or otherwise aggressive can wear them down, requiring expensive replacement.

Drum liners can help mitigate or even eliminate these problems.

Made from flexible or semi-rigid polymers, drum liners protect both the drum and the product inside. They make cleaning easier, and can even remove the need for it entirely in certain closed-loop applications. They serve as an additional barrier for the product, protecting it from both contaminants on the drum’s inside walls and the outside world in general. They also keep the drum from constant contact with the product, extending its life and making it a better candidate for reconditioning or recycling when it does reach the end of its usefulness.

CDF Corp. makes a range of drum liners to fit all the relevant variables in a drum application: product type and viscosity, sanitary requirements, static hazards, and evacuation method. Straight-sided liners are available for 12-, 16-, 30- and 55-gallon drums. For 55-gallon drums (the most common bulk shipment size), four structural variations are available:

Straight-sided: This is most often recommended for highly viscous products that must be evacuated by a pump with a follower plate that descends into the drum, squeezing the product upward.

Accordion liners: These have pleats that allow them to adjust in height. They are suitable for users who have to fill drums of varying heights and do not want to store multiple sizes of liners.

Combination liners: These have sides that combine a band of accordion pleats with straight walls. They are good for users who have to use a follower-plate pump but need to accommodate different drum heights.

Vented inserts: These liners include four holes near the top to vent trapped air during a fill, allowing drums to be filled with the lid on.

Other specialized liners include anti-static liners, which are designed to eliminate static that can build up during filling with powder and become a nuisance (or worse), and hot-fill liners that can withstand temperatures of up to 350°F.

Drum linersCDF Corp. also has useful accessories for drum filling, including strainer inserts, interior and exterior lid covers, and dust caps.

Reduce Hazards with Anti-Stat Drum and Pail Liner Choices

Static electricity is not just the annoyance that zaps your finger, makes your hair stand on end, and makes your clothes cling. It can be a killer.

Static electricity is the precipitating agent in many industrial accidents caused by improper handling of liquids, powders, and bulk solids. Such products can build up electrostatic charges as they are being conveyed, filled, discharged, or otherwise put in motion. If the equipment and the bulk packaging that handles the material is not properly designed, and safety procedures like grounding are not followed, a spark caused by static electricity can ignite an explosion which could have deadly consequences.

Most industrial accidents caused by static electricity occur in facilities that handle plastics, fuel, solvents, paints, and other highly flammable materials. However, food manufacturing plants are by no means immune. According to Health and Safety Executive, sugar, flour, custard powder, instant coffee, dried milk, potato powder, soup powder, and other powdered or bulk solid foods have the potential for static electricity explosions. One of the worst such accidents in modern history occurred in 2008 at the Imperial Sugar refinery near Savannah, Georgia, killing 14 people and injuring 42 more.

“Unfortunately, these hazards are generally not as well recognized as they should be, but they constitute a serious safety concern for manufacturers and their employees,” Caitlin Lucia, a senior process engineer at Campbell Soup Co., told Food Manufacturing magazine. “They can also be a potential hazard for the communities surrounding production facilities.”

Understanding Conductivity

One of the most important factors in static electricity explosions is the conductivity of equipment and packaging. Materials with low conductivity (i.e., high electrical resistance) constitute a greater danger, because they allow the buildup of electrons on their surfaces, raising the potential of sparking. The risk of explosion rises with finely ground product, and when flammable materials like edible oils, solvents, or cleaning chemicals are used close to potential sources of electrostatic sparks.

Drum and pail linersFood plants often use plastic liners with steel drums and pails for improved sanitation and evacuation efficiency. Unfortunately, plastic is an inherently non-conductive material, which, as noted above, raises the risk of sparking. However, specially treated plastic can greatly reduce that risk. CDF Corp. offers antistatic drum and pail liners that dissipate electrostatic charges before they can build up and cause sparking.

These liners are available in both military-specification (mil-spec) and NFPA (National Fire Protection Association) standards. The difference is basically in the parameters of the tests that the materials must pass to meet the standards. Differentiating factors include how long it takes a surface static charge to decay, at what temperature and humidity. (Generally speaking, the MIL standard is stricter.)

Anti-stat liners have benefits beyond reducing the risk of sparks. They reduce clinging dust for improved sanitation and appearance; they provide protection against drum and pail corrosion; and they protect drums and pails for longer life.

6 Advantages of Industrial Flexible Liquid Packaging

Flexible packaging is taking the world by storm. It’s preferred by manufacturers, wholesalers, retailers and end-users. Its popularity isn’t just a trend. For nearly all dispensable products, there’s a flexible packaging possibility.

What can it do for you? Check out these 6 advantages.

#1: Appropriate for Many Different Industries

You’ve probably seen flexible packaging for single-serve fruit drinks and household product refills, such as laundry detergent. But did you know that it safely keeps bulk quantities of health and beauty products, salad dressings, chemicals and paint fresh? Versatility is one dominant characteristic that separates flexible materials from rigid packaging.

Flexible liquid packaging

From warehouse to pantry, smaller packaging fits where traditional packaging can’t.

#2: More Efficient Use of Storage Space

How much storage space do you need for daily operations? With flexible packaging, you’ll probably need less. Even with bag-in-box styles, containers are smaller when empty and smaller when full. That gives you more mileage from your storage space. The space-saving nature of flexible packaging also benefits transportation costs and carbon emissions. Smaller, lighter containers require fewer vehicles, fewer trips and create fewer carbon emissions in the process.

#3: Variety of Container Dimensions and Styles

From ounces to gallons, flexible packaging offers so many options, there’s probably at least one that suits your needs. Choose from several different films, such as the standard laminated polyethylene/nylon, high-barrier laminated polyethylene/EVOH/nylon or metalized polyethylene/metallized polyester.

#4: Durability in Lightweight Packaging

Don’t let flexible packaging fool you. It’s lightweight, but also tough. Bag-in-box containers use significantly less plastic than rigid or semi-rigid containers. CDF1 Smart Seal Technology™ monitors each seal in every liner bag for consistency and stores data for future reference. And a series of in-process tests, including a visual inspection, further ensures the integrity of every bag.

#5: Virtually Limitless Branding Options

Packaging Digest suggests that when it comes to branding possibilities, flexible packaging is just getting started. It’s malleable and lends itself to almost limitless graphic designs. For example, photochromatic ink responds to sunlight, making branding messages appear or disappear. And with clear designs and better inks, the brand message looks sharp and consistent.

#6: Quick Rollout of Packaging Modifications

Ordinarily, a product update, such as a new flavor or color or an ingredient change, requires an expensive shift in production. But with flexible packaging, rollout of a new product or alteration is fast and simple. Maybe you want a different tap style, a custom liner or new graphic design. Or maybe the change is temporary, such as for a seasonal product. Whatever the modification, flexible liquid packaging adapts fast to keep production on time.

Anchor Printing says, “Brand leaders have the responsibility to keep their products dependable, secure and easy to distribute without any shipping disasters.” That sums up the CDF philosophy in a nutshell.

In an era where less really is more, flexible packaging delivers. Download our Bag-In-Box brochure to learn more.

Plastic Packaging Better for Environment than Alternatives Made with Other Materials

A recent life cycle assessment analyzed the energy and climate benefits of alternative plastic materials in contrast to plastic material. The categories included caps and closures, beverage containers, other rigid containers carrier bags, stretch/shrink wrap, and other flexible packaging materials. Carol Hochu, President and CEO of the Canadian Plastic Industry Association noted, “Plastic packaging enables the safe and efficient delivery of various products which form part of our daily lives, everything from food to essential health and safety aids. However, many are unaware that plastics carry out these functions while at the same time conserving energy and lowering greenhouse gas emissions.”


In Canada, the LCA found that replacing all plastic packaging the non-plastic packaging would:


  1. Require nearly 4.4 times as much packaging material by weight. Increasing by nearly 5.5 million tons.
  2. This would also increase energy use by 2.0 times. This was calculated as being equivalent to the amount of oil transported by 18 supertankers
  3. This would result in 2.3 times more global warming potential. This was equated to adding 3.3 million more cars to the road.


Engineering in plastic packaging enables innovation and performance – the ability to extend the shelf life of foods and medicines. Plastic packaging viewed from the entire life cycle have more benefits than the snapshot that has been taken in years.


The afterlife of plastic is further contributing to sustainability in many ways. The ability to recycle, reuse and repurpose for energy value and converted to liquid oil, electricity and into other fuels.


There have been great strides made in the reusability and repurposing of plastic containers. These valuable resources are used to make fleece jackets, new plastic bottles, pipes, pallets, creates and buckets, decking and other lawn and garden products. The majority of product stemming from recycled plastic bottles, non-bottle rigid plastics such as deli and dairy containers, bakery, vegetable, fruit containers, and plastic film, bags and outer wrap.


Plastic enhances our lifestyles, our economy, and the environment.
