What GelPax customers say
Feedback from customers of our custom gel pack range.
“I was quite cautious when first ordering from Gelpax.com because I was worried it would be a difficult process and they would be too expensive. But after I got the product and used it for orthopedic surgeries I was very happy with the quality and performance! They were also great at matching my logo colors.”
“I currently use the 3x5" Gelpax for the kids at my school when they get hurt. I absolutely love them! Especially the size and how durable they are. Not to mention the low price! I can't imagine how any ice packs could be better.”
“Here at Twin Cities Foot and Ankle, we use the 4" Round Gelpax to promote our brand. I love how they have a fabric backing on one side. It makes them much more comfortable on the skin. Their customer service is unparalleled.”
“When I first looked at the Gelpax website, I had a few questions. I called them and they immediately answered. I got my sample shortly after that and was very happy with it. I love how affordable the product is while still holding exceptional quality.”
“I loved the customization on my Gelpax. I especially liked how it's inside the pack, making it impossible to remove. I used them to treat my patients and they work really well. I'd recommend Gelpax to anyone.”
“When I saw Gelpax online I knew they were the right product for me. I use them to promote my brand and they work fantastically! Not to mention that they look great. The price is reasonable and the quality speaks for itself.”
“I chose Gelpax because of their unmatched quality. I use them to treat patients and love how they have a fabric backing on one side of the 4" round. There's nothing I would change about our Gelpax and would definitely recommend them!”
“I chose Gelpax because of their great customer service. The 3x3" works great for giving to patients post treatment. I love all the great sales and offers they have. I would recommend Gelpax to anyone looking for an easy way to promote their practice.”
“These custom Gelpax work great for treating patients while also promoting our practice. I love how small the 3x3" is, it really looks nice. I can't think of anything I would change about this awesome product!”
“Being in Alaska it was really important that I had a cost effective way to get the Gelpax here. Brooke worked with us to make sure that the shipping was affordable. We use the Gelpax for post injection care for our patients. They seem to love how comfortable the 4" round is on the skin.”
“Here at Janiga MDs, we decided to go with the 3x5" Gelpax for treating our patients because we really liked how nicely made the product is. We are totally satisfied with our choice and wouldn't change anything about our Gelpax.”
“We went with Gelpax because of the price of their 6x10" packs. We love using them to hand out to our new patients as part of their first exam/appointment. Not to mention how cool it is to have my own image on the front of it.”
Insulation and cooling work together
An insulated liner slows heat transfer through your shipping carton. Gel packs provide cooling. Choose both around the goods, required temperature and transit time.
The liner is one part of the complete shipping configuration. Holding time depends on your insulation, refrigerant, payload and shipping conditions. Box liners are supplied separately from shipping boxes.
Insulated shipping liner questions
Are thermal box liners and insulated shipping liners the same thing?
These terms commonly describe insulation placed inside a shipping carton. The name alone does not specify the material, thickness, closure or usable space. Compare those details, and the evidence for your shipping conditions, before choosing a liner.
Does the liner include a shipping box?
This category is for insulated liners, not shipping boxes. Tell us the carton you use; the quote will identify exactly what is included.
Do I still need ice packs?
That depends on your required product temperature and shipping conditions. Liners provide insulation, while refrigerants supply cooling capacity. Evaluate the complete configuration together.
Which measurements should I send?
If available, send the carton’s internal length, width and height plus your payload dimensions. You can submit an inquiry without measurements and provide them later.
Do I need a specification before contacting you?
No. Enter the number of liners you need and your contact details. Add carton dimensions in shipment notes if you have them, or provide them when we follow up.
What are the minimum order and delivery time?
We confirm the available configuration, minimum order, stock or production lead time, freight and transit estimate in your quote. An inquiry is not an order or a delivery commitment.
Can you help with recurring orders?
Tell us your expected usage and delivery locations. We will discuss quantities and replenishment requirements before proposing commercial terms.
