Success Story

Our medium sized square jam jars for canning and silver lids with an embossed berry design were chosen by an organic berry farm based in Washington State. The results of these custom designs were outstanding: the square jars have earned them a 20 percent efficiency increase in their packaging line, and the sophisticated and individualized appearance earned them a contract with the premium line of a national supermarket chain, which means an expansion to 500 stores. On the basis of this, they ordered 200,000 more jars to be ordered in summer fruit harvesting season and their new handmade jam line.

Jam Jars for Canning Customization Recommendations

• Custom Frosted Label Panels: Have even, frosted rectangles on one side or both sides of the square jars so that they would adhere well to the label and to avoid stains.
• Embossed Lid Design: Choose a custom embossed logo, farm name or fruit/vegetable design to emboss the top of the metal lid to make it look fancy.
• Lid Lining Choices: It has lids that can be lined in various materials (e.g. BPA-free plastisol, PVC-free) where there is a lot of acid or oily food.
• Anti-Slip Texture: Add some slight vertical textures or a frosted finish to the sides of the square jars in order to have better grip.
