About inner container liner

Types of Inner Container Liner

Suppliers usually provide these types of inner container liners in bulk to business owners.

Plastic liners

These types of container liners are produced from films made of woven polythene or polypropylene. Plastic liners are used as water proofseals to protect goods and products against moisture, dust, and other harmful elements. They are very lightweight, easily fitted into containers, and cost relatively low and moderately priced. However, they can puncture and tear easily and may not be suitable for transporting dangerous goods since they do not offer resistance to chemicals.

Paper liners

Paper container liners are manufactured from heavy-duty industrial paper. Paper liners are commonly used to hold bulk dry products such as grains, powders, and seeds. They help in contaminant protection and provide an eco-friendly solution because they are recyclable and biodegradable. The major demerit is that they lack water and moisture resistance, and wet or humid conditions can weaken the liner.

EPDM rubber liners

EPDM liners are manufactured for containers using Ethylene Propylene Diene Monomer, a synthetic type of rubber. Due to their wide temperature range, EPDM liners are especially helpful when shipping products that may be affected by extreme heat or cold. Their flexibility makes them suitable for use in containers of irregular shapes, and their resistance to UV and ozone degradation provides them with longer outdoor uses. However, due to their dense nature, they can be relatively expensive.

Foam liners

Fleece liners are produced from different types of foam, which are intended to go inside containers for the safe packing of products during shipment. Foam liners are produced in different types, such as polyurethane or polyethylene, and have excellent cushioning, absorbing shocks and vibrations that might damage fragile items like glassware, electronics, or medical equipment. They will be suitable if transporting temperature-sensitive goods, as some foam liners have cooling properties. Foam liners also produce soundproof liners that prevent thieves from stealing sensitive products while in transit. However, liners are relatively expensive, and a damp environment can a destroy foam.

They are used to store and transport bulk ingredients like sugar, flour, grains, and liquids such as oils, syrups, and juices. Special liners are coated to give them food-grade safety for safe food transport. Moreover, paper liners provide an ecologically safe solution for carrying sundry food ingredients while maintaining hygiene. Indeed, the liners are recyclable.

Mining and metals industry

In mining and metallurgical operations, mineral ores, concentrates, and chemicals are transported in containers with liners. Container liners help protect minerals and mine materials by averting water and chemical interaction, which negatively affects the material. Foam liners are made strong enough to contain heavy and rough items, so they are suitable for the mining industry.

Pharmaceutical and healthcare industry

In the pharmaceutical and healthcare segment, the significance of maintaining purity and sterility cannot be overstated. Container liners safeguard active pharmaceutical ingredients (APIs), bulk powders, and medical devices from sweltering contaminants, moisture, and air. Foam liners are suitable for fragile medical equipment or temperature-sensitive products. Plastic liners are produced with materials that have sanitation compliance in the pharmaceutical industry.

How to install

The following are the general steps on how to install an inner container liner: Prepare the container: Inspect the container for any residuals or sharp objects that could damage the liner. Ensure the container is clean and free from debris. Unfold the liner: Remove the inner bag from its packing and unfold it. The liner material should be fitted to the container with any openings facing up. Insert the liner: Carefully place the liner into the container, ensuring that it lines up with all the container's corners and sides. The liner should cover the entire interior surface of the container. Attach the liner to the container: Depending on the kind of liner and container used, the liner can be attached with static adhesion, magnets, or adhesive spray. Make sure the liner is tightly affixed so no openings develop between the liner and container. Spread the liner: As the liner is being spread, ensure it is flat and smooth without any wrinkles or folds that might hinder it from doing its work. If it is a fleece liner, you may have to apply some force. Fold the excess liner over the container top edge to create a cuff. This allows the liner to better basket the load and helps keep it in place. The cuff also makes it easier to close the liner after loading. Once the liner is properly positioned around the container, use clips or tie-downs to secure the liner to the container's top edge. This keeps the liner stable during transport.

How to use
