Integration drives innovation at Multifilm. With in-house extrusion, metallization, and a small lab line that lets us test new resins quickly and easily we are constantly working on creating a better mousetrap. Hi-E is similar to its sister product Hi-Z in that it is a high-barrier, metallized sealant web, but Hi-E is specifically designed for bag film applications. Hi-E can be laminated to reverse printed polyester (PET) or oriented polypropylene (OPP). The result is a high-gloss, high-barrier film with an easy-open function and hermetic seals.
Hi-E is a polyethylene-based film, and has been in the works for years. Traditionally, the main problem with metallized sealant webs is getting the metal to adhere to the film. As a result, many metallized bags are made of three webs, leaving the sealant web un-metallized. Hi-E can accomplish the same thing as metallized bags made of three webs, but using just two webs. The result is less material and fewer production steps, therefore lower cost, less material, and ultimately less garbage in our landfills. A Hi-E laminate can easily reduce the amount of material used by 20 percent or more.
Perhaps the most exciting aspect of Hi-E is the barrier values. Independent testing confirms a moisture barrier of less than 0.01 g/100 in2/day and a gas barrier of less than 0.1 cc/100 in2/day. This is better than metallized PET, metallized OPP, and PVdC coated PET. Hi-E is on par with extremely expensive, specialty films like Alox and Siox, but at a fraction of the price.
Hi-E is the ideal candidate to replace virtually any metallized triplex structure, but Hi-E is ideal for the fractional pack coffee market. It’s a very competitive industry that has been hammered by record high PET prices. When laminated to OPP, Hi-E offers reverse printing, a superior barrier, and a lower price.
