Custom Inserts in St. Paul, MN
St. Paul is Minnesota's state capital and the Twin Cities' more historically rooted and culturally diverse partner — a city with a large Hmong-American community that has made it a center of Southeast Asian culture and commerce, a state government economy, a nationally recognized food scene that has emerged in the Frogtown and Hamline-Midway neighborhoods, and a growing arts and creative community in the Lowertown warehouse district. My Custom Boxes serves St. Paul's diverse and government-anchored business community with premium custom packaging.

Why Choose Our Custom Inserts
Custom Packaging Inserts | Foam, Thermoformed & Corrugated Product Inserts
Custom packaging inserts transform the interior of a standard box into a precisely engineered product presentation system — securing items against movement during shipping, presenting products at the optimal viewing angle for unboxing, and communicating brand values through the materials and precision of the insert design itself. Our custom inserts are manufactured from a range of materials calibrated to the product's weight, fragility, and presentation requirements.
Insert Material Options
- EVA Foam: The most versatile insert material — CNC-cut to any product profile in densities from 1.2 to 6.0 lb/ft³. Used for electronics, jewelry, cosmetics, medical devices, and precision instruments
- Polyethylene Foam: Standard protective foam for heavier products and shipping applications — excellent shock absorption and compression resistance
- Corrugated Cardboard Inserts: Die-cut corrugated dividers and partitions for multi-unit packaging — cost-effective and recyclable
- Thermoformed Plastic Trays: Precision-formed PET or PVC trays with individual product cavities — standard for cosmetics, electronics, and food packaging
- Molded Pulp: Sustainably produced from recycled paper fiber — used for premium electronics, wine, and fragile product inserts as a plastic-free alternative
- Velvet-Flocked Foam: EVA foam with velvet flock coating for jewelry and luxury goods presentation
Insert Design Principles
Effective insert design begins with the product's center of gravity and fragility points. The insert must prevent movement in all six directions during shipping while presenting the product face-up at the correct angle for unboxing. For multi-product packaging, the insert must maintain consistent product spacing regardless of manufacturing tolerance variation in individual product dimensions.
Foam Insert Engineering for Product Protection
Foam insert engineering is not guesswork — it is an applied science. The insert material density is selected based on the product's weight (lighter products need lower-density foam that compresses easily to absorb energy; heavier products need higher-density foam that provides firm support). The cavity geometry is designed with 0.5–1.0mm tolerance around the product to prevent movement without making insertion difficult. Drop test simulation determines whether the cavity design successfully absorbs the impact energy from a standard 30-inch drop test — the pass/fail standard for parcel shipping.
Molded Pulp: The Premium Sustainable Insert
Molded pulp inserts — produced from recycled paper fiber formed over precision molds — have emerged as the premium sustainable alternative to thermoformed plastic trays for electronics and fragile product packaging. Apple's iPhone packaging uses molded pulp inserts; premium whiskey brands use molded pulp bottle cradles; premium headphone brands use molded pulp to cradle their products. The material is 100% recyclable, compostable, and manufactured from post-consumer recycled content — a premium sustainability story that brands communicate proudly on their packaging.

Custom Inserts in St. Paul — FAQs
What foam density should I use for my product?
Low-density foam (1.2–2.0 lb/ft³) provides soft cushioning for lightweight products under 2 lbs. Medium-density foam (2.0–4.0 lb/ft³) is standard for most consumer products from 2–10 lbs. High-density foam (4.0–6.0 lb/ft³) provides firm, stable support for heavier products and precision instruments. We can recommend the optimal density based on your product weight and shipping channel.
What is a thermoformed insert?
A thermoformed insert is a plastic tray formed by heating a flat sheet of PET or PVC film and drawing it over a custom mold to create three-dimensional cavities that match your product's shape. Thermoformed inserts provide precise, rigid product support and are standard in cosmetics, electronics, medical device, and food packaging applications where consistent cavity geometry is critical.
Can you make inserts for multiple products?
Yes. Multi-product inserts use either foam with multiple cavities cut to each product's profile, thermoformed trays with individual product sections, or corrugated divider systems that create separate compartments within the box. Multi-product inserts must be designed to accommodate manufacturing tolerance variation in individual product dimensions while maintaining consistent presentation.
What is molded pulp and why is it considered premium sustainable packaging?
Molded pulp is produced by forming recycled paper fiber slurry over precision aluminum molds and drying it to create three-dimensional shapes. The result is a structurally precise, 100% recycled, recyclable, and compostable insert material that requires no petroleum-based plastics. Premium electronics and spirits brands use molded pulp to communicate sustainable packaging credentials alongside the quality of their product.
