A Guide to Contract Packing
What is contract packing?
Rather than packing its products in-house, a manufacturer or retailer can outsource the job to a contract packing company (often called a contract packer).
The contract packer then packs the products for redistribution. Typically, the products go straight to market.
Contract packing, contract packaging and co-packing what’s the difference?
There isn’t one these are all different names for the same service.

What services does a contract packer offer?
Contract packers often provide a number of services, including the following:
Vertical form fill seal (VFFS)/Vertical bagging
The packing machine vertically creates the bag as it packs the raw material. As the top of one bag is sealed, the bottom of the next bag is created.
Pouch packing involves filling products in hangable or standalone bags. It’s a versatile packing method that’s ideal for food products and powders, and even lends itself to liquids thanks to a protective laminate layer.
Sachet filling is a cost-effective method for sealing small products that are usually dosed or portion-controlled. It’s an automatic process that uses vertical bagging techniques to pack dry products, powders and liquids.
This involves the manual packing of products that can’t be filled by machinery or automated on the production line. Hand assembly often includes the filling of large containers or boxes with unique or customised orders.
Filling pre-made packaging with a product. The product is accurately measured and dispensed by machines to ensure the exact dose is present in each unit for quality assurance.
Specifically focusing on liquids, this process involves filling bottles with the product and packing the bottles to the highest standard in bulk.
Rework and rectification
Packaging rework, also known as repacking or package restoration, is the reparation of damaged packaging to make products fit for sale. This may include reorganising products, repacking them into fresh containers or attaching new stickers, tags or barcodes.
The high-speed and cost-effective sealing of solid products in an airtight film as they run along a conveyor.
Wrapping a product (or group of products) in a thick, tight polythene sleeve. Unlike shrink wrapping, both ends of the sleeve are left open. This makes it easier to stack items on pallets and protects them against damage and dirt during transit.
A process that uses heat to shrink a plastic film, which wraps tightly around the product to create an airtight layer. This keeps the products fresh and also protects them from becoming damaged during movement.
Wrapping a finished product with an outer layer of film to provide extra protection and a luxury appearance.
Filling bottles with a liquid product and packing those bottles in bulk. Just as with contract filling, the product is accurately measured and dispensed by machines to ensure the exact dose is present in each unit for quality assurance.
Packing products in a pre-formed plastic casing that is backed by plastic or cardboard.
Injecting inert gas into the packaging to flush out oxygen and prolong shelf life.

Why should we use a contract packer?
Perhaps your business manufactures and ships items in bulk to keep costs down. You package the products for transportation only-meaning they aren’t yet ready for retail.
Rather than invest in machinery, staff and training to pack the products yourself, you can outsource this work to a contract packer.
Do use a contract packer if you:
- lack the right equipment or expertise in-house
- are working to full capacity but unable to meet demand
- are soft-launching a product and don’t want to commit the finances needed to pack in-house
- have a product which is available only temporarily, such as a promotion or a trial
- have run into operations problems—for example, you’ve laid off staff or your current packing lines need maintenance
- don’t have storage space, as normally you import products and send them straight to store
- simply want to control your costs
Don’t use a contract packer if you:
- lack the capacity or finances to put the contract packager’s suggestions or recommendations into practice
- are working with small product runs
- have the proper equipment in-house
How do we hire one?
Choose the ideal contract packaging company for your business by following the process below.
1. Work out exactly what you need
Clearly identify your needs or what specific problem you want the contract packaging company to solve.
Consider your budget honestly and carefully, as it’s easy to underestimate how much packaging can cost. If the contract packer has experience and provides a high-quality service, it should be able to assess how to adjust your project to keep it within your budget.
2. Find potential candidates
Compile a shortlist of options and contact each company. Ask the following kinds of questions:
- Have you worked with products similar to ours?
- What challenges have you faced, and how did you overcome them?
- What general contract packing experience do you have?
- Can you provide references?
- How do you determine the cost of a project?
- What quality control and production control processes do you use? Do you have any industry accreditations?
What size company you should use
Bigger isn’t always better, but at the same time the contract packer must have the capacity to deal with your product lines.
Smaller contract packers are often better at developing custom solutions with you and can pay you more attention. They may be more invested in your product.
However, if you have a very large production line, make sure the contract packer can prove it has the capacity to cope with it.
Where the company is located
Take account of where the contract packer is based, as you can save on the cost of transporting goods from your manufacturing base to the packing site.
However, often the money you’ll save on outsourcing your packing can outweigh the cost of getting the product to site.
3. Meet in person
The packaging process is often complex and varies from job to job, so organise a face-to-face meeting with the company to discuss your project.
Be open to suggestions. Contract packagers are used to coming up with innovative solutions to problems.
4. Ask for proposals
Request a project proposal from each candidate on your shortlist. Make sure they explain:
- the scope of work—a general description of what they will do for you
- what services they will provide
- what the project will cost (and provide a schedule for payment)
5. Finalise and sign a contract
Fine-tune the details of the proposal and sign a contract packing agreement with the packing company.
6. Stay in touch
Make sure you remain in good communication with the contract packaging company. This will help them to get to know your business and operations quickly.
Does a contract packer pack any product?
It depends what specific production lines it operates. Generally, the machines a packing company uses don’t restrict it to one particular type of product (for example, just cosmetics or just food).
A contract packer will typically deal with a range of products, from toys to electronics, cosmetics to food, and even more specialist products like chemicals or ionised water.

How does food contract packing work?
Food can be packed in lots of different types of packaging. Most food is packed using methods where the packaging is already made and then filled.
Food in sachets will be packed using a technique known as vertical form fill seal. Solid foods like chocolate bars can be pushed along a conveyor belt and packed using horizontal bagging techniques such as flow wrapping.
A customer can either supply the packaging themselves or have the contract packer source it for them.
How much does contract packing cost?
Prices vary a lot from customer to customer, as every job is different. Here are some factors that affect the total cost of the job:
Quantity—small runs usually cost more than large ones
Type of packaging—some options are more expensive to make, and so have a higher price
Print options—printing designs onto packaging adds to the cost, although digital printing can bring the price down a little
Audits—customers often want to audit a contract packer’s service before hiring them, which also adds to the overall cost
