Glue is a small part of a larger whole but critical to many manufacturing processes. Customers often ask us how they can get the most out of their adhesive. Below are some of the experts' best cost-saving advice for gelatin and liquid glue applications.

Consider Highly-Concentrated Gelatin Adhesive

Look for gelatin glue sold in blocks or “cakes” rather than in a bag. In cake form, gelatin glue has a higher solids content and tends to be more cost-effective to ship and apply. 

Since it has less water content, it is more economical to ship than bagged gelatin glue. Gelatin glue in block form can be diluted up to 5 to 10% to other adhesive formulas. 

If you are having challenges with measuring the percentage of solids in your glue, a refractometer can help.

Check Glue Application Depth

Are you applying the right amount of glue? The recommended about of gelatin glue to apply using a roller is about 2 to 3 mils. You might be applying too much if your glue doesn't set correctly. 

We sometimes find that customers are applying up to 5 mils of gelatin glue in some cases. Not only are you wasting glue, but you are slowing down your production line. 

Using a MIL Depth Gauge is the best way to check if you are applying the right amount of glue. Simply hold the gauge against your roller or the substrate immediately after the adhesive is applied to measure the thickness. We have free Mil Depth Gauges for manufacturers.

Know the Shelf-Life of Your Glue

Natural adhesives expire after a certain amount of time. Gelatin glue generally has a shelf-life of one year if kept in a cool, dry place. If kept in optimal conditions, it may last longer.

Water-based liquid glue has a "manufactured date" rather than an expiration date. The expiration date varies depending on when the container is opened. Once the adhesive is exposed to air, it has a shelf life of around 90 days. 

This means buying glue in bulk is a good practice. Some businesses tend to look only a month or so ahead of time in their orders. By purchasing a 3 to 6 months supply of adhesive at a time, companies can save money in the long run on shipping.

Check out the chart below to estimate how much you can save by buying gelatin glue in bulk.
