Custom corrugated, folding cartons, rigid boxes, labels, and more. Built to your spec, printed to your brand, delivered fast.
Custom packaging is part structural engineering, part brand design. Done right, it protects your product in transit, communicates quality the moment someone picks it up, and turns a delivery into an experience.
Since 2003, Guardian has helped California businesses get custom packaging that fits their product, their brand, and their budget. We handle the spec work so you don’t have to guess.
Six custom packaging formats Guardian designs, sources, and delivers for California businesses.
RSC, die-cut, auto-bottom, and specialty corrugated in any flute (B, C, E, BC). Single or double wall. Custom print up to 4 colors, or kraft natural finish.
Paperboard cartons for retail shelf, DTC mailers, and product inserts. UV coating, foil stamping, embossing, matte laminate. SBS, CCNB, or specialty substrates.
Set-up boxes with magnetic closures, ribbon pulls, and custom liners. Premium finish for cosmetics, electronics, gifting, and luxury DTC. Minimum runs available.
Roll and sheet labels in any size. Pressure-sensitive, waterproof, and food-grade options. Flexo or digital print for short or long runs.
Custom-printed poly mailers, zip bags, and stand-up pouches. Resealable, tamper-evident, and biodegradable options. DTC-ready, ships in 2-3 weeks.
Floor stands, counter displays, and PDQ trays with custom print. Corrugated or chipboard construction. Designed for retail placement and brand visibility.
From first conversation to finished product. Simple, transparent, no
surprises.
Product dimensions, quantity, material preferences, and any branding assets you have. The more detail, the faster we can quote.
We come back with pricing and, when needed, a structural prototype so you can see fit and function before committing to a print run.
Our team preps your artwork for print and sends a digital proof. No surprises at press. You approve before we run.
Production runs and ships to your facility or fulfillment center. California-based warehousing means faster lead times than most suppliers.
Not every packaging supplier is worth the extra mile. Here’s what you get when
We don’t hand you a template and walk away. Our team works through structural design and print-ready artwork with you, especially on complex formats.
Fit matters. We spec your box to your actual product weight and dimensions so it survives transit without being over-built and expensive.
California warehousing and direct vendor relationships cut weeks off typical custom lead times. We’ll be honest about timelines upfront.
Recycled content corrugated, FSC-certified board, biodegradable poly, and soy-based inks. We’ll help you find the right sustainable spec for your category.
Pantone matching, CMYK calibration, and press proofs to keep your brand colors consistent across every run and every format.
Family-owned means you talk to the same person from quote to delivery. No handoffs, no “let me check with the team” runaround.
From first-run startups ordering 500 units to established brands shipping hundreds of thousands of boxes a year, we've built custom packaging programs at every scale.
We don't just fill orders. We help you figure out the right spec the first time, so you're not paying to redo a bad run.
