Packaging Equipment Buying Guides

Buying a packaging machine takes four decisions in turn: what to ask for, how to compare the replies, how to confirm the machine does what was agreed, and what it will cost to run. This section has a tool for each. It is written for buyers, plant and production managers, and the engineers, maintenance and quality staff who support them.

What this section covers

• A reusable RFQ template that lists the information suppliers need to quote a packaging machine.
• Factory and site acceptance testing, and how to write acceptance criteria both parties can verify.
• A total cost of ownership framework for comparing offers on a lifecycle basis.
• Questions to put to suppliers and documents to request at each stage.

It does not cover legal contract drafting, financing, used equipment, supplier rankings or product recommendations. It does not give prices, delivery times or performance figures. Choosing a machine type is covered in the packaging section, and line connections and maintenance are covered in the automation and plant operations sections.

Core selection questions

Before suppliers can quote, they need at minimum the product, the package and materials, the output, the site, the interfaces, the controls, the documents and the acceptance method. The RFQ checklist puts these in nine sections.

The machine type to ask for depends on the product and package format. The overview of machine types shows where each type sits in the line and links to the comparisons.

Heights, transfers, signals, buffers and safety zones must be agreed before design if the machine is to fit the line. The integration checklist covers them.

Packaging material and machine have to match in tension, friction, marks and sealing behavior. The guide to film and machine compatibility lists the properties, and trials confirm them.

Acceptance criteria are written before the tests: test object, duration and sample quantity agreed by both parties, measurement method, pass or fail rule and sign-off. The FAT and SAT guide explains how.

To find which offer costs less over its life, compare acquisition, operation, maintenance, downtime and changeover, and end-of-life costs on the same basis, then test the assumptions. The total cost framework provides the structure.

A faster machine in a line limited elsewhere may add cost but no output. The guide to bottlenecks in packaging lines shows how to check whether the machine is the constraint.

How to use these guides

The guide map shows a purchase in five steps, and what each step should produce. Defining needs produces a machine type and comparisons. Writing the RFQ produces the checklist. Comparing offers produces a cost framework. Ordering and building produces a specification and a factory test plan. Acceptance and hand-over produce criteria for the factory and site tests.

Read the guides in step order even if you are already partway through. A buyer who has received quotations may find that gaps in the RFQ explain why offers are hard to compare. A buyer who has ordered but not agreed acceptance can still write criteria before the factory test. The step outputs are documents you carry from one stage to the next, so each stage builds on what the earlier one settled.

Key terms used in these guides

Term	Meaning in these guides
RFQ	A request for quotation: the written information sent to suppliers so they can quote
Specification	The agreed technical description of what the machine must do and be
FAT	Factory acceptance test, carried out at the supplier’s site
SAT	Site acceptance test, carried out in your plant on your line
Acceptance criteria	The written test object, method, pass or fail rule and sign-off agreed before testing
Total cost of ownership	The sum of acquisition, operation, maintenance, downtime and changeover, and end-of-life costs over a chosen period
Sensitivity	How much a comparison changes when an assumption changes
Interface	A defined connection between the machine and the line, site or utilities
Hand-over	Transfer of the accepted machine, documents and training to the operator

Common mistakes to avoid

• Writing a request that names a machine but not the product, package and output. Suppliers then quote their own assumptions, and the quotes cannot be compared.
• Ranking offers on purchase price alone. Changeover time, scrap, energy and maintenance differ between machines and can change the order.
• Agreeing acceptance after the order. Criteria written once the machine is built tend to follow what the machine does instead of what you need.
• Testing with samples that are easier than production product. If the product varies, include the variation in the trial.
• Letting a quotation’s “or equivalent” items go unchecked. Ask for them to be named and compared.
• Treating the supplier’s rated speed as proven. It has to be demonstrated on your product, under the conditions you agreed.

How this section connects to the rest of the site

Buying decisions draw on every other section. The packaging section helps define the machine type and pack format, and its overview of machine types is the usual first step. Controls and interfaces that go into the RFQ are covered in the automation section. The plant operations section explains the maintenance and changeover effort that feeds the cost comparison, and materials and inspection covers the film and inspection requirements that belong in the specification.
