OTC Packaging Guide

OTC packaging requires more than putting a product into a box. Brands need to consider packaging format, labeling, quality requirements, production accuracy, retail presentation, scalability, and how the finished product will move through the supply chain.

The right OTC packaging partner should understand the operational requirements behind the product and be able to consistently execute the approved packaging configuration.

This guide explains what OTC packaging involves, which capabilities brands should evaluate, and what to ask before selecting a contract packaging company.

What Is OTC Packaging?

OTC packaging refers to the packaging operations used to prepare over-the-counter products for distribution, retail, or the end customer.

Depending on the product and project, those operations may include primary packaging, labeling, secondary packaging, cartoning, multipacking, kitting, retail display preparation, quality inspection, warehousing, and fulfillment.

Some brands perform these operations internally. Others work with a contract packaging company that provides the labor, equipment, processes, facilities, and production capacity needed to complete the packaging program.

Why Does OTC Packaging Matter?

Packaging is one of the final operational steps before an OTC product reaches distribution, a retailer, or the consumer.

Errors made during packaging can create problems far beyond the packaging line.

Depending on the program, packaging mistakes may include:

• Incorrect labels
• Wrong packaging components
• Missing inserts
• Incorrect product counts
• Damaged cartons
• Incorrect SKU configurations
• Outdated artwork
• Incorrect retail packs

A strong packaging process is therefore built around consistency, documented requirements, quality controls, and clear communication.

How Does the OTC Packaging Process Work?

Every OTC packaging program is different, but a typical project may move through the following stages.

1. Define the Packaging Requirements

The product, packaging format, volume, SKU count, components, labeling requirements, timeline, and final configuration are established before production.

2. Review Components and Specifications

Packaging materials, labels, cartons, inserts, product information, production instructions, and other requirements should be reviewed before the project reaches the packaging line.

3. Prepare the Packaging Operation

The packaging provider establishes the production process, equipment, labor requirements, quality checks, and material flow needed for the program.

4. Perform Packaging and Assembly

Products are packaged according to the approved specifications. Depending on the project, several operations may be completed in sequence.

5. Complete Quality Checks

Defined checks help confirm that finished goods match the approved project requirements.

6. Prepare Finished Goods

Finished products may be packed into shipping cases, prepared for retail, placed into displays, transferred to warehousing, or moved toward fulfillment and distribution.

Common OTC Packaging Formats

OTC products can appear in many packaging formats depending on the product, consumer use, retail channel, and applicable requirements.

Common packaging formats may include:

• Bottles
• Cartons
• Pouches
• Sachets
• Blister configurations
• Multipacks
• Kits
• Display-ready cartons
• Retail trays
• Point-of-purchase displays

A single product may also use several packaging layers.

Why Is Labeling Important in OTC Packaging?

Labeling is a critical part of many OTC packaging programs because the label connects the physical product to its approved product information and packaging configuration.

Packaging teams need clear control over which label, carton, insert, and artwork version belongs to each SKU.

A packaging program may need to control:

• Correct label selection
• Correct SKU
• Artwork version
• Placement
• Lot or production information when applicable
• Packaging component matches
• Retail configuration

Exact requirements depend on the specific OTC product, packaging format, and applicable regulatory and customer requirements.

How Should Quality Be Managed in OTC Packaging?

Quality should be built into the packaging process rather than treated as a final visual check.

Before production begins, the brand and packaging partner should clearly define what the finished product is expected to look like and which requirements must be verified.

Depending on the project, checks may include:

• Correct product
• Correct components
• Correct label
• Correct artwork version
• Correct count
• Correct carton or kit configuration
• Package appearance
• Finished case configuration

For regulated products, brands should also ensure their packaging program aligns with the applicable regulatory, quality, and documentation requirements for that product.

What Role Does Secondary Packaging Play in OTC Products?

Secondary packaging surrounds or groups already packaged products.

For OTC brands, that may include cartons, multipacks, display-ready packaging, kits, retail trays, and shipping cases.

Secondary packaging can serve several functions at once:

• Protect finished products
• Group units together
• Organize products for retail
• Support merchandising
• Provide additional brand communication
• Prepare products for distribution

This is why secondary packaging should be considered early in the project rather than treated as an afterthought.

How Should OTC Brands Prepare Products for Retail?

Getting a product packaged is not always the final step.

Products entering retail may need specific carton configurations, multipacks, trays, displays, case packs, labels, or other retailer-specific preparation.

Brands should understand those requirements before the packaging program is finalized.

Ask:

• How many units belong in each case?
• Will the product require a display?
• Does the retailer require a specific configuration?
• How will the product be presented on shelf?
• Will packaging need to support multiple retail channels?

How Do You Choose an OTC Packaging Partner?

Choosing an OTC packaging company should involve more than comparing unit prices.

Evaluate how the provider will support the entire program.

Experience

Ask whether the provider has experience working with similar products, packaging formats, volumes, or industries.

Quality Systems

The provider should be able to clearly explain how requirements are documented, production is controlled, and finished goods are checked.

Capacity

Make sure the company can support current production needs and potential growth.

Multiple Capabilities

Consider whether the company can support packaging, kitting, secondary packaging, displays, warehousing, and fulfillment if the project eventually needs those services.

Communication

You should know who manages the project, how approvals are handled, and how production changes are communicated.

Scalability

Ask what happens if production volume increases, more SKUs are added, or the product expands into new channels.
