Box liners play a crucial role in the packaging of various industries, encompassing commercial fisheries, poultry processing, primary and secondary packaging for pharmaceutical products, as well as the transportation of hygroscopic materials like machinery, powders, and other moisture-sensitive items.
Due to numerous factors, packages frequently experience delays in shipment, endure exposure to harsh weather conditions, encounter harmful bacteria and hazardous chemicals, and suffer from damages. Regrettably, it's not always feasible to control these external influences on your package. However, by utilizing our Mylar box liners, you can significantly mitigate the harm caused by these adverse conditions.
Our box liners, combined with our internal atmosphere creating sachets, offer the flexibility to create any desired enclosed environmental conditions. These ready-to-use box liners are constructed from robust Mylar foil material, available in various sizes, ranging from 5” x 5” x 12” to 17” x 17” x 12”, and thickness options spanning from 2.5 mils to 5.0 mils. Should your requirements exceed these dimensions or thicknesses, don't hesitate to Contact Us. We possess the capability to design and produce custom box liners tailored to meet your specific dimensional needs.
How to find proper bag size for a box liner:
Find the Length (L), Width (W), and Height (H) of the box.
Width of bag: Length (L) + Width (W) + 2”
Length of bag: Width (W) + Height (H) + 2”
For example, if box size is 16”(L) x 6”(W) x 20”(H), then
Width of bag: 16”(L) + 6”(W) + 2” = 24” Wide
Length of bag: 6”(W) + 20”(H) + 2” = 28” Long
Bag size needed is 24" x 28"
Ensuring optimal protection for your product requires carefully considering the following points:

IMPAK produces custom printed pouches and packaging with an emphasis on materials with distinctive barrier properties to protect products from the adverse effects of moisture, oxygen, light and more. Learn about our unique custom capabilities.
High barrier bags are used to preserve and protect products. When paired with an oxygen absorber or desiccant, products enjoy even greater shelf-life and stability. However, selecting the appropriate package is not always as straight forward as it seems.
Not every Industrial Vacuum Sealer applies to every application. There are different models and types of Vacuum Sealers available, and each one of those sealers has different features that can affect the way a production line works.
