Reusable packaging. Reusable packaging is manufactured of durable materials and is specifically designed for multiple trips and extended life. A reusable package or container is "designed for reuse without impairment of its protective function." The term returnable is sometimes used interchangeably but it can also include returning packages or components for other than reuse: recycling, disposal, incineration, etc. Typically, the materials used to make returnable packaging include steel, wood, polypropylene sheets or other plastic materials.

Reusability of packaging is an important consideration of the environmental credo of "reduce, reuse, and recycle". It is also important to the movement toward more sustainable packaging. Returnable packaging is encouraged by regulators.

Shipping containers
For many years, several types of shipping containers have been returnable and reusable. These have made most sense when a reverse logistics system is available or can be readily developed. A return, reconditioning, and reuse system can save money on the cost per shipment and can reduce the environmental footprint of the packaging.

Manufacturing, particularly the automotive industry, has used heavy-duty returnable racks for shipping hoods, fenders, engines, dashboards, etc. from suppliers to final assembly plants. The racks are then returned for the next shipment cycle.

Bulk foods, chemicals, and pharmaceuticals are often shipped in reusable and returnable containers. These need to be carefully inspected, cleaned and sanitized as part of the reuse cycle. An effective quality management system is necessary.

Wooden pallets are often made to be expendable, for a single shipment. Others are heavy duty and intended for multiple shipments. Some are in "pallet pools" which are used, inspected, and refurbished for extended usage.

Often reusable industrial shipping containers have bar code labels or radio-frequency identification (RFID) chips to help identify and route the containers.

Use in the automotive industry
Automotive original equipment manufacturers (OEMs) use and encourage the use of returnable packaging to move components from their vendors to their factories. The components are placed in returnable packaging and are at times and arranged in a way that facilitates movement straight to assemble lines. Such packaging replaces traditional corrugated cartons, thereby helping companies cut costs by avoiding wastage and effort required in disposing the cartons. It also helps in reducing the environmental footprint of the automotive industry.

Other advantages of using returnable packaging include avoiding damages to parts in while in transit. Parts are at times placed in specially designed receptacles for easy picking on the assembly line contributing to fewer mistakes and simpler inventory management.

A few examples of returnable packaging in automotive industry:

Consumer packaging and containers

Several types of consumer containers have been in reuse systems. Reusable bottles for milk, soda, and beer have been part of closed-loop use-return-clean-refill-reuse cycles. Food storage containers are typically reusable. Thick plastic water bottles are promoted as an environmental improvement over thin single-use water bottles. Some plastic cups can be re-used, though most are disposable.

Home canning often uses glass mason jars which are often reused several times.

Many non-food types of containers, including reusable shopping bags, and luggage, are designed to be reused by consumers.

With any food packaging, proper cleaning and disinfecting between each use is critical to health.

In September 2019, the UK Environment, Food and Rural Affairs Committee released a report claiming that the official intervention should encourage more shops to offer refillable options instead of traditional single-use packing.

Reuse for other purposes

Used packages are often reused for purposes other than their primary use. For example, a single-use plastic shopping bag might be reused as a bin bag, a household storage bag or a dog faeces bag. Steel drums can be reused as traffic barricades, dock flotation, and as musical instruments

Justification
Reusable packaging often costs more initially and uses more and different materials than single-use packaging. It often requires adding complexity to the distribution system. Not all packaging justifies being returnable and reusable.

A thorough cost analysis is required. This involves all of the material, labor, transport, inspection, refurbishing, cleaning, and management costs. Often these costs may be incurred by different companies with different cost structures.

The environmental costs and benefits can also be complex.  The material, energy, pollution, etc. needs to be accounted for throughout the entire system. A life cycle assessment offers a good methodology for this task.
