The modern-day packaging market is competitive, fast-paced, and a matter of cents. For a beverage manufacturer, an FMCG supplier, or a manufacturer of consumer goods, the costs associated with packaging can determine whether or not their business is profitable. The main source of those costs is typically the production of plastic PET preforms.
The majority of companies historically manufactured preforms in-house to ensure an adequate supply of product and control over their quality. However, many companies are beginning to shift their mindset away from the “do-it-yourself” model of PET preform manufacturing, to opting to outsource that function to a specialized supplier — and enjoying the benefits associated with that shift.
In this blog post, I will provide insights on why outsourcing is not simply a way to save money, but instead is a way for brands to position themselves for future success, grow their businesses, improve quality, and remain competitive.

Why preforms matter in packaging
For a bottle manufacturer or brand based on bottles, preforms have direct implications for:
- The strength and durability of the product: A properly-formed plastic bottle resists deformation throughout its lifetime.
- The branding of products: Clear, consistent, and shiny finishes are significant factors in how consumers view bottled products and companies.
- Operational efficiencies for bottling Lines: Bottle lines function better with properly formed preforms.
- Financial management of production costs: The savings achievable by reducing preform weight, no matter how small, can reach several lakhs of rupees each year.
For these reasons, many companies are reevaluating whether they should handle their own preform production or outsource to a company specializing in plastic bottle production.
The rise of outsourcing in the packaging industry
Outsourcing packaging isn’t something that’s new. Companies have been doing this for some time by outsourcing their logistics, warehousing, and raw materials. Recently, companies have started to outsource the manufacturing of plastic PET preforms.
Why have companies decided to outsource their Preforms? It takes a significant investment in equipment, machinery, molds, skilled labor, and quality control systems to manufacture the preforms. For many brands, this is not their expertise; therefore, they rely on the capabilities of a manufacturer that specializes in the production of preforms.
Through outsourcing the manufacturing of Preforms, they can reduce risk, optimize the supply chain, and utilize their capital in areas where they receive the highest return.
5 Hidden benefits of outsourcing PET preforms

Most companies think about reducing their costs when outsourcing a service. However, the main benefit from outsourcing comes from the benefits received that may not be seen immediately as cost savings.
1. Reduced capital expenditure
Establishing an Internal production site for the production of plastic injection-molded (i.e., PET) preforms is capital-intensive (i.e., millions in capital investment). These costs include the cost of new, high-precision injection molding machines, the cost of new molds for plastic preforms of various neck sizes, the cost of utilities, and the cost of ongoing maintenance.
When brands outsource their plastic preform production, they do not have to incur the above costs, and their capital can be used for either R&D or expansion into new markets.
2. Access to expert technology
In general, specialized suppliers (i.e., plastic bottle manufacturers) invest heavily in advanced injection molding and automation technologies. The outsourcing option allows companies access to these advancements without the investment needed to purchase or maintain this complex, high-quality equipment.
For example, specialized plastic bottle manufacturers produce:
- High-cavitation molds to accommodate high-volume production.
- Real-time monitoring systems to ensure consistent weight and dimensions.
- Multi-layered preforms for improved shelf-life and sustainability.
As a result, these technical advancements help with improved quality for plastic bottle manufacturers, but these manufacturers do not have to bear the additional financial cost to upgrade their existing technologies.
3. Improved consistency and quality control
Consistency throughout the millions of preforms manufactured in-house is one of the largest challenges faced by a preform producer. Even the smallest discrepancies can stop production prematurely and lead to unacceptable conditions at either the appliance or packing line.
There are benefits to outsourcing the production of plastic bottles to a manufacturer who provides a constant flow of plastic bottle-grade resins with:
- Standardised quality checks for each batch.
- A history of producing error-free batches at all levels.
The result is less hassle for those within purchasing departments, as well as less disruption during the production cycle.
4. Better supply chain efficiency
When a company produces its own resin grades, it takes on the additional responsibilities and risks of labour shortages, machine downtime, or limitations in access to resin supplies.
By outsourcing, none of these responsibilities or risks is transferred to the producer. An established outsourced producer will have the production capacity, redundancy, and logistics capabilities that are needed to provide uninterrupted resin supplies. An outsourced production partner will, therefore, be able to:
- Reduce the need for large resin inventories.
- Provide on-time production of resin or preforms.
- Be able to respond quickly to spikes in demand.
Outsourcing allows plastic bottle manufacturers to minimise production bottlenecks and increase flexibility.
5. Cost savings through economies of scale
The volumes of plastic PET produced by specialist plastic bottle manufacturers typically exceed 1,000 tons per year. Because of this, these companies can negotiate lower resin costs and operate their machinery much more effectively than smaller manufacturers, and also can spread their overhead costs over a larger volume of products.
Brands that outsource their plastic PET preform production to these manufacturers gain access to the economies of scale that larger manufacturers can achieve with their larger-scale operations; the costs associated with having in-house operations would likely be impossible to attain for smaller manufacturers.
Why plastic bottle manufacturers are embracing outsourcing
Interestingly, outsourcing isn’t just a strategy for brands — even some plastic bottle manufacturers themselves outsource It is interesting to note that brand owners are not the only ones using outsourcing; plastic bottle manufacturers also outsource preform manufacturing. By partnering with a specialized manufacturer of plastic PET preforms, the manufacturer can reduce the high shipping costs associated with this supply chain and instead concentrate on their blow-molding operations.
With this strategy, manufacturers can:
- Eliminate expensive equipment investment.
- Create more floor space for bottle manufacturing.
- Speed up production by only focusing on their core competencies.
As a result, the supply chain will become a more streamlined and efficient network whereby each supply chain segment is performed by a specialist.
What to look for in a reliable outsourcing partner

Finding a good partner to outsource production to is essential for success. Not all plastic bottle manufacturers and preform distributors provide the same quality, production capacity, or levels of service. When evaluating potential suppliers, several factors must be assessed:
- Production Capacity: Is the supplier capable of servicing customers’ needs for both a steady and seasonal production demand?
- Customization: Is there flexibility in the production process, such as in the weight, color, and neck-width of the bottles?
- Technology: Does the supplier employ modern, automated technologies to ensure accuracy in the production of the products?
- Quality Assurance: Does the supplier have an established system in place to ensure that every batch produced is consistently checked for quality?
- Sustainability Practices: What are some of the ways that they are incorporating recyclable materials into their manufacturing process and/or reducing their overall energy usage?
- Location and Logistics: By locating closer to a bottling plant, transportation costs and lead times can be minimized.
The true value of outsourcing comes when there is a reliable and trustworthy supplier who can fill the role of a long-term business partner.
