RSC, die-cut, mailer, and specialty corrugated boxes. Built to your spec, printed to your brand, shipped from California.
Corrugated is the workhorse of packaging, but not all corrugated is the same. Flute selection, board grade, wall count, and print method all affect how your box performs in transit and how it looks when it arrives.
Guardian has sourced and supplied corrugated for California businesses since 2003. We spec to your actual product weight and dimensions so you’re not paying for overkill and not getting boxes that fail on the line.
Six corrugated formats covering general shipping to specialty industrial applications.
The industry standard for distribution and e-commerce. Available in single, double, and triple wall. Custom print up to 4 colors flexo, or litho-label for premium retail presentation.
Full-overlap flaps add a double layer of protection on top and bottom. Preferred for industrial equipment, glass, and high-value fragile goods.
RETF, auto-bottom, and crash-lock styles. Designed for unboxing experience and fast pack-out. Strong enough to ship without an outer shipper.
Custom-shaped blanks for products that need a precise fit or enhanced shelf presentation. Handles, windows, and custom inserts available.
Two-piece design (lid and base) for adjustable depth. Common for artwork, apparel, and industrial parts that vary in length or height.
Five-Panel Folder (5PF) for long parts, Half-Slotted Container (HSC), One-Piece Folder (OPF) for books and flat goods, and Wraparound Blanks for canned goods and bottles.
Corrugated applications across the sectors Guardian serves most.
Right-sized mailers with custom inserts. Reduces damage, cuts dimensional weight charges, and delivers an unboxing moment worth posting.
Moisture-resistant liners, FDA-safe materials, and ventilation options. RSC and die-cut formats for produce, bottles, and packaged goods.
Double and triple-wall construction for heavy components, tools, and machinery. Edge protection and custom inserts available.
Anti-static options, precision die-cuts, and foam insert integration for sensitive components and high-value devices.
Four print methods covering every volume and budget level.
Most economical for large runs. Clean, consistent branding on kraft or white liner. Best for stock-style boxes with a logo or basic brand mark.
No plates, fast setup, full-color output. Ideal for prototypes, seasonal SKUs, and small quantity runs where flexo minimums don’t make sense.
High-resolution litho sheet laminated to corrugated. Premium retail presentation with photographic quality. Best for cosmetics, gifting, and shelf-facing boxes.
Gloss varnish, soft-touch matte, emboss/deboss, and foil accent options. Adds tactile quality that flat print can’t achieve.
Recycled content board (40-100% PCW), FSC-certified options, and water-based inks. We’ll spec the right sustainable option for your product category.
We spec to your actual product dimensions. No padding, no unnecessary airspace. Right-sizing reduces material cost and dimensional weight shipping charges.
Yes. We can pull stock samples for standard styles and produce structural prototypes for custom die-cut or specialty formats. You test fit, board strength, and appearance before production starts.
We coordinate delivery across Orange County, Los Angeles, San Diego, and the Inland Empire. Rush delivery windows are available when needed.
Minimums vary by box style and print method. Digital print allows smaller quantities (as low as 50-100 units). Flexo and litho-label runs typically start at 500-1,000 units. Contact us and we’ll give you a real number based on your spec.
