We've teamed up with Kwik Lok, the originator of the first bag closure, to help innovate a new tamper evident closing machine using our fiber laser. The laser stitches the bag closed and prevents tampering with the food inside the bags.
http://www.matthewsmarking.com/product/laser-coding/ Matthews offers a complete line of CO2 and fiber laser marking systems to suit your marking and coding needs. Our lasers are designed to fit a number of industrial and packaging applications, whether you need to mark in static or continuous mode, and onto a variety of materials, such as glass, plastic, paper, cardboard, foils, coated metals, and building materials.
For food, beverage, and pharmaceutical packaging applications, as well as for assorted industrial applications such as plastics and metal pipe, continuous inkjet (CIJ) printing is an ideal choice for printing date, time, batch codes, text, barcodes and logos. Print at speeds up to 1050 feet/minute, and character heights from .05" to .61" (1.25mm -- 15.6mm.) Use high resolution inkjet when you need the highest quality print on your corrugated boxes and other porous materials. Often a substitute for pre-printed labels or boxes, high resolution inkjet affords you the convenience of on-demand printing of batch and date codes, variable text, graphics, and barcodes, eliminating your need to stock such costly items. Matthews' Viacode T-Series and HX64 high resolution printers operate using piezoelectric technology. The robust printheads create dark, crisp images with print heights up to 3.94" (100mm) from a single printhead. Our superior ink efficiency, and re-circulating auto-prime function, contributes to up to 35% less ink consumption than competing brands.
