Zenpack is a full-service packaging agency that integrates custom packaging design, manufacturing, global freight, climate-controlled warehousing, kitting, e-commerce last-mile shipping, and retail channel compliance across facilities in North America, China, Taiwan, Southeast Asia, and Central America.
How Does Packaging Design Affect Freight and Shipping Costs?
Integrating structural packaging design early in pre-production directly minimizes shipping expenses by maximizing container volume and reducing pallet dimensional weight. Pairing this with optimization software and flexible international transit planning helps brands reduce wasted cargo space and downstream supply chain delays.

Freight Packaging Optimization
Pallet loading and shipper optimization software, lightweight and paper pallets, and custom wood crating maximize container capacity. On Fitbit‘s Surge smartwatch line, this approach maximized space efficiency across a six-material kit.

International Freight Services
Navigating ocean freight, air freight, and Less-than-Truckload (LTL) shipping with local customs brokers and freight forwarders across major trade routes.

Fulfillment By Amazon (FBA) Management
Inventory arrangement, container optimization, and negotiation with Amazon warehouses to minimize storage fees.
What Does Packaging Fulfillment and Assembly Include?
Packaging fulfillment and assembly cover everything between a finished production run and a product reaching the customer: custom-insert assembly, multi-SKU kitting, climate-controlled warehousing, and last-mile e-commerce delivery.
Zenpack handles the entire process through a single network, with facilities across Southeast Asia, China, Taiwan, the US East and West Coasts, and Central America via Amevel.


Assembly & Custom Inserts
“Pack ready” packaging engineered with custom inserts to reduce labor hours, minimize downtime, and handle volume surges.
Package Kitting (Stock & On-Demand)
Integrating kitting considerations early in the package design phase to save inventory space and reduce overall shipping costs.
Strategic Warehousing & Just-in-Time Delivery
Climate-controlled facilities situated near global manufacturing hubs (Southeast Asia, China, Taiwan, US East & West Coasts, and Central America via Amevel) offer just-in-time capabilities for inventory fluctuations.
E-Commerce Last-Mile Fulfillment
Software integration for online sales channels and discounted rates with domestic and international carriers including FedEx, UPS, and DHL.
How Does Zenpack Solve High-Complexity Kitting?
The Challenge
Jim Beam needed a 60-unit influencer mailer for its Cadillac F1 partnership — a batch too small for custom metal tooling, built around an off-the-shelf toolbox with rolled safety edges that left a top opening narrower than the interior cavity. The kit also had to protect fragile glassware inside a rigid metal shell with zero shock absorption, all under a fixed pre-race-day deadline.

Zenpack’s Solution
Custom trapezoidal foam inserts: Engineered EVA foam cutouts shaped wider at the top and narrower at the bottom so they slide past the narrow rolled edge without warping.
Interference-fit glass protection: Undersized foam cutouts created a tight wrap that immobilized the glassware, passing internal drop tests without redesign.
The Results
60 flawless units delivered: Hand-selected from a production run of 260 under an artisan appearance standard, meeting the Miami Grand Prix deadline.
Zero shipment damage: Every unit individually bagged, boxed, and foam-lined for transit — arriving intact and driving strong social engagement around the F1 launch.
What Does Retail Channel Compliance Involve?
Retail channel compliance means meeting each retailer’s packaging, quality, and print standards before a product reaches their shelves or warehouses. Falling short can lead to shipment rejections, costly chargebacks, or loss of vendor eligibility with that retailer.
Because every retailer’s requirements differ, Zenpack ensures clients meet their target retailer requirements, ranging from on-site quality audits and GMI-certified printing to FSC-certified sourcing and other retailer-specific requirements.

FAQ
Zenpack operates climate-controlled warehousing across Southeast Asia, China, Taiwan, the US East and West Coasts, and Central America through its partnership with Amevel.
Package kitting bundles multiple SKUs or components into a single retail-ready unit, planned during the design phase to save inventory space and reduce shipping costs. Brands typically need it for multi-item product launches, subscription boxes, or promotional bundles where components would otherwise ship and store separately.
Yes, Zenpack sources FSC-certified materials and follows ESG-compliant supply chain practices as part of its retail channel compliance process. This is bundled into the same audit and sourcing process used for retailer-specific compliance, not offered as a separate add-on.
