Custom Packaging for Co-Packers & Contract Packagers

The right packaging supplier can help contract packagers reduce assembly problems, manage material availability, support changing volumes, and provide customers with a more complete packaging solution. PM Packaging works with co-packers, contract packagers, manufacturers, and brands to develop custom packaging around the product, production process, sales channel, and delivery requirements.

A package may look successful in a rendering or prototype but still create problems on the production floor. Before the structure is finalized, the packaging supplier should understand how the product will be packed. Important considerations include:

• Whether the package will be assembled manually or automatically
• How the product will be loaded
• Whether an insert is required
• How the package will be closed
• Where labels will be applied
• How completed units will be inspected
• How the packages will be placed into master cases
• How many units must be packed per shift

A package with too many folds, tabs, or separate components may slow a manual operation. A carton designed without considering existing equipment may not run reliably on the co-packer’s line. An insert that is difficult to load may create inconsistent product placement. Custom packaging should therefore be engineered for both the product and the people or equipment assembling it.

Custom printed cartons coordinated directly with contract packaging logistics.

Folding cartons can provide a compact, printable format for retail products, kits, replacement components, food products, cosmetics, medical products, office supplies, and other consumer goods.

They can be developed with tuck closures, glued closures, auto-lock or crash-lock bottoms, hang tabs, windows, interior partitions, paperboard inserts, tamper-evident features, and product-specific openings.

For co-packers, the carton style should match the required assembly speed and closure method. A simple tuck carton may be appropriate for a short manual program, while a pre-glued or machine-compatible structure may be more suitable for higher-volume production. The graphics, barcode locations, product identification, and legal information should also be coordinated across every SKU.

Corrugated packaging may be used for master cases, ecommerce shippers, retail-ready trays, displays, and heavier products. The correct structure depends on product weight, stacking, shipping exposure, case-pack quantity, and pallet configuration.

Custom corrugated packaging can help co-packers protect completed retail packages, maintain consistent case counts, improve pallet stability, reduce product movement, support ecommerce delivery, create retail-ready shipping cases, organize kits and multipacks, and simplify distribution handling.

The master case should be developed around the finished primary package. If the carton dimensions are changed without reviewing the shipping case, the co-packer may experience inefficient case packing, excess void space, or an unexpected change in pallet quantity.

Single face lamination, commonly called SFL, combines a printed paperboard surface with corrugated material. This format can be useful when a program needs more structural support than a folding carton but a more refined presentation than a conventional corrugated box.

For co-packers, SFL can sometimes combine functions that would otherwise require multiple packaging layers. The structure may provide the printed appearance of primary packaging while also adding rigidity for distribution. The package should still be evaluated around the actual product load, pack-out method, insert requirements, and shipping environment.

Blister cards can be effective for small products that benefit from visibility, organized peg display, tamper evidence, and printed technical information. Common applications include hardware, small tools, automotive parts, electronics accessories, stationery, and cosmetics.

A blister-card program requires coordination between the printed card, formed blister, sealing method, product orientation, and pack-out equipment. The card coating and blister material must be compatible with the sealing process. The blister cavity must hold the product securely without making loading unnecessarily difficult, and the hang area must support the weight of the filled package.

Inserts can improve product retention, presentation, and pack-out consistency. They may be made from paperboard or corrugated material and can be designed to hold products in place, separate components, protect delicate surfaces, organize accessories, and present products in a planned sequence.

For a co-packing program, the insert should make product placement clear and repeatable. Each component should have a defined position so packers can identify missing or incorrectly placed items quickly. The insert and outer package should be developed together to avoid excess material, poor product fit, and unnecessary assembly steps.

Contract packagers frequently manage product families containing multiple flavors, colors, sizes, quantities, models, languages, or retailer-specific versions. A multi-SKU program may involve different printed cartons using the same structure, shared inserts, variation-specific blister cards, and different case-pack quantities.

Deliveries must be coordinated with production. Packaging materials must arrive when the co-packing line is ready to use them. An early delivery may create storage problems, while a late delivery may stop production entirely. The packaging supplier should understand production dates, delivery windows, receiving hours, and SKU separation requirements.

Physical prototypes can help identify pack-out problems before full production begins. A prototype allows the co-packer and brand to evaluate product fit, insert performance, assembly time, closure security, case packing, and pallet efficiency.

The prototype should ideally be reviewed by the people who will assemble the package. Their feedback can identify difficult folds, unclear loading steps, and components that may slow production. Testing with the actual product is essential, as weight, tolerances, and irregular features often affect performance in unpredictable ways.
