Keeping Custom Calf Feeding Bags Ready Between Uses: Cleaning, Storage and Durability Checklist

Leaving a calf feeding bag wherever it lands after use may feel convenient, but it shortens the bag's working life. Trapped milk residue, dampness and dust create the conditions for mould and odour, while sunlight, rodents and crushing pressure weaken the film until it cracks or tears. The problem often surfaces only when the next feeding is due, costing time and money. As a producer of spout pouches, bag-in-box (BIB) liners, colostrum bags and liquid packaging bags, KODY PACK outlines the farm-level habits that help custom calf feeding bags stay ready for use.

1. Wash First, Then Dry the Bag Thoroughly

Key points:

• Flush the interior with warm water several times to remove milk leftovers and film; a mild neutral detergent can help with stubborn residue, but rinse all soap away afterwards.
• Focus on the spout, outlet and seams, where dirt collects most easily and mildew tends to appear first.
• After washing, hang the bag upside down to drain, or wipe it gently inside and out with a clean towel.
• Complete drying usually takes one to two days, depending on weather. Storing a bag before it is fully dry seals moisture into the container and defeats the purpose.

2. Choose the Right Storage Environment and Containers

• Aim for dry, cool and light-blocked conditions. Direct sunlight accelerates ageing in plastic or laminated film, making bags brittle and easier to tear.
• A well-ventilated shed or barn is a practical choice. Avoid basements and other damp areas, and do not let bags sit against walls or on bare floors where they can absorb moisture.
• A temperature- and humidity-controlled storeroom is even better for keeping bag condition stable.
• For containers, strong plastic baskets can hold several bags while allowing some airflow, which helps them stay dry.
• If baskets are not available, large lidded plastic bins work, provided they are clean. Label the outside with bag type and size so you can find the right bag quickly later.

3. Organise by Type and Keep Pests Away

• Stack bags neatly in the container. Group different sizes together, and store colostrum bags separately from standard milk bags so nothing slows you down at feeding time.
• Rodents and insects can chew through bag material, and a single puncture makes the bag unusable. Keeping the storage area clean and free of food scraps is the most effective pest control step.
• Mothballs or natural essential oil repellents may be used, but keep them away from the bags to avoid odour or ingredient contamination.
• If bags are kept in a shed, seal wall gaps and holes to cut off pest entry routes.

4. Inspect Periodically and Consider Bags Built for Longer Storage

• Even when bags are just sitting in storage, check them every few months for cracks, holes or mould; remove any damaged bag immediately so it does not affect others in the same container.
• Use the inspection as a chance to rotate stock, using the longest-stored bags first to keep inventory moving.
• For better storage durability, consider aluminium foil colostrum bags: the foil layer adds an extra barrier against light, oxygen and moisture, and is also harder for rodents and insects to damage.
• Colostrum bags with a feeding tube are convenient, but pay special attention to the tube during storage — keep it clean, wrap it in a clean cloth or place it in a separate plastic bag, and prevent crushing or deformation.

The service life of a calf feeding bag is often lost in storage rather than during use. Make these steps part of your farm routine, and your bags will remain ready for the next feeding. KODY PACK has long supplied spout pouches, bag-in-box (BIB) liners, stand-up pouches with taps, colostrum bags, liquid packaging bags and laminated roll film to food, personal care and liquid packaging customers, with custom specifications and structures available.
