Common Uses, Types of Container Liners and Advantages

Shipping certain materials can sometimes be inefficient. Using container liners can help make shipping these materials much easier, saving you time and money. Container liners are perfectly suited for shipping minerals, powders, seeds and food. Ours are made from polypropylene (PP) and polyethylene (PE).

Using PP and PE container liners has several advantages. They’re a very cost-efficient tool to use that will help prevent cross-contamination. If you aren’t using container liners, you must be cleaning out the inside of the container between each transport or using one container for only one type of material. If you’re transporting a chemical powder in one trip and then a food item on the next, you can’t risk the food getting contaminated. Using polypropylene or polyethylene container liners will prevent these problems.

Container liners are easy to install and can be reused. If you ship the same material often, you can label the liners for the type of materials that they hold. When you’re not using the container liners, you’ll find that they’re lightweight and can be folded up to be stored almost anywhere.

Container liners also eliminate packaging waste that’s unavoidable in other packing methods. Without using container liners, you would have to package the goods into smaller containers to keep them from spilling and make sure they stay safe. With a container liner, you can skip that step by packing the goods directly into the container.

Polypropylene Container Liners and Polyethylene Container Liners

Midwestern Bag & Supply offers premium polypropylene and polyethylene container liners. We design our shipping container liners from these materials because they allow for the smooth conversion of any ISO package into an effective bulk transport process. We want to make sure you implement a shipping system that guarantees success. With our liners, your fine, dry goods such as food products, granules and powders will get to where they need to go in good shape.

As you’re deciding whether to choose a polypropylene or polyethylene container liner, it’s important to consider the strengths and purposes of each material.

Polypropylene (PP) Container Liner Suppliers You Can Trust

We line our polypropylene packaging with a reliable coating that allows for unmatched weathering and UV resistance. These liners can last a number of years, so they’re well worth the investment.

Polypropylene is known as one of the longest lasting and strongest geomembrane liners available on the market. Its impermeability and through-the-floor chemical resistance render it a favorable choice for high-profile containment applications like municipal waste treatment.

Use these bulk container liners for evaporation ponds, retention pond liners, nursery pond liners, reservoirs and even temporary oil pit/lagoon liners.

Adaptable Polyethylene Bulk Container Liners for Any Industry

Polyethylene is yet another strong, impermeable material. This package liner will prevent any moisture from passing through, ensuring your products stay safe and dry. Most polyethylene containers can be heat sealed, meaning your goods will travel from point A to point B in an air-tight shipping container liner.

The versatile nature of polyethylene packaging creates numerous opportunities for your business. We can custom design your liners in different thicknesses and clarities for your particular products.

From food products and fine powders to retail goods and liquids, these liners can handle it all.

Specifications for Bulk Shipping Container Liners

Our shipping container liners provide an affordable, protective and valuable packaging alternative — they will transport your products in a safe, dry and contaminant-free package. We also offer custom, bulk container liner designs for specific applications. They include the following:

  1. Gravimetric, loading directly from silos: If you are loading powders and granules direct from the silo, we can prepare your packaging design to aid in efficient and effective transport.
  2. Pneumatic, loading using the door end bulkhead: For loading materials like powders and resins, using a specific dry bulk container liner makes a big difference.
  3. Loading via the end bulkhead conveyor: We offer tailored container liners for goods including malt, cocoa, coffee and soybeans.
  4. Gravimetric and pneumatic, discharging by emptying spout or letterbox system: It’s important to ensure your packaging specifications fit with this method of loading. Otherwise, the job may be more difficult than necessary.
