Custom printing transforms a commodity poly bag into a branded packaging experience. Whether you need a simple one-color logo or a full multi-color design, here is what you need to know about custom printed poly bags.
The Printing Process
Most poly bag printing uses flexographic printing — a high-speed rotary process that transfers ink from engraved plates to the film surface. Flexo printing is ideal for poly bags because it handles large runs efficiently and produces consistent results on flexible substrates.
What You Can Print
- Company logos and branding
- Product information and descriptions
- Barcodes and QR codes
- Regulatory text (suffocation warnings, recycling symbols)
- Nutritional facts and ingredient lists (food packaging)
- Batch numbers and date codes
Design Specifications
Colors: Flexo printing supports up to 8 spot colors per design. Each color requires a separate printing plate. PMS (Pantone) color matching available for brand consistency.
Artwork: Provide vector files (AI, EPS, PDF) for best results. Minimum line width is typically 0.5 points. Halftone screens can simulate gradients and photographs but solid colors produce the sharpest results on poly film.
Print area: Most of the bag surface is printable, with small margins at the edges and seal areas. Your specific print area depends on bag size and style.
Plate Costs and Minimums
Custom printing requires printing plates — a one-time tooling cost that varies based on design size and number of colors. Plates are reusable for repeat orders. Minimum order quantities for printed bags are typically higher than stock bags due to press setup time.
