Gel packs preserve the shelf life of products and ensure they remain in the same condition as when they were packed. Gel packs are pouches filled with water or refrigerant gel that can be frozen and remains frozen longer than just ice when used for packaging perishable products. The purpose of gel packs for food and pharmaceutical items is to maintain the appropriate temperature range during transportation. These food grade gel packs are made in Canada and come in different sizes, including 16, 24, 48, and 64oz. They are safe, reusable, 100% recyclable, and non-toxic.
How long will Gel Packs Remain Frozen?
The main contributor to keeping gel packs cold is proper cold chain packaging. Typically, gel packs remain frozen for up to 6 hours if accompanied by insulated shipping liners. The following are five major factors that contribute to how long gel packs remain frozen:
1. The number and size of gel packs used.
The number of gel packs present in an insulated shipping container will determine the duration of time that the products will be maintained within the temperature range. Also, the larger the gel pack, the longer it will take to defrost.
2. The type of insulation used to line your shipping box.
Proper insulation provided from different insulated shipping liners will help preserve gel packs’ freezing time.
3. The amount of void space in your box.
If there is a lot of space within the box, hence extra air circulating, the gel packs will not be as efficient.
4. The outside temperature during shipping.
If the products are being shipped in warm or hot temperatures , more insulation and/or gels may be needed to maintain the integrity of the shipment.
5. Transit time from your location to the destination of your box.
Gel packs remain frozen for up to 6 hours, so it is important to keep in mind the transit time of a shipment.
The thick, puncture-resistant, pressure-tested outer pouch guarantees a longer life for gel packs. The gel packs can be used ambient, refrigerated, or frozen and handled with bare hands, making them reliable and easy to use. It is recommended to freeze gel packs for a minimum of 24 hours before shipping to ensure they stay frozen for as long as possible.
Different Types of Gel Packs
There are a few different options to choose from when it comes to gel packs. Some options include antimicrobial, blue industrial grade, and drain-friendly gel packs that can be included in an insulated shipping container. An antimicrobial gel pack is a good option for use with food as it will not lead to bacterial contamination due to the outer layer. It is specially treated to ensure bacteria does not grow.
