Tube Filling and Sealing Machines for Plastic, Laminate and Aluminium Tubes: What You Can Specify Before the RFQ

Screen first on substrate and format envelope

Substrate capability is the cheapest disqualifier you have. If a machine's declared tube range does not cover the ABL or aluminium tube you fill, no price or speed advantage recovers it.

Settle this before you compare anything else. One publisher reports that cosmetic and pharmaceutical tube filling machines handle plastic (HDPE, LDPE, PP), aluminium barrier laminate (ABL), plastic barrier laminate (PBL) and all-aluminium tubes, at 13–60 mm diameter and 5–400 ml fill¹⁷.

The same source lists creams, gels, ointments, pastes, lotions, toothpaste, pharmaceutical topicals, adhesives and medical device gels as the products served¹⁷. Treat that envelope as a starting specification to put to each supplier, not as a market limit — it is one publisher's reported range.

Your first check is therefore documentary: ask each supplier to state in writing which of the four substrates their machine runs and the diameter and fill-volume limits for each. A supplier who answers for plastic only has told you where the shortlist ends.

Fix the pump from your product, not from the substrate list

A machine that lists all four substrates has not told you how it will dose your cream, gel or paste. The same source states that product viscosity determines the pump type required, and that this must be confirmed with the supplier at specification stage¹⁷.

Substrate capability and dosing configuration are separate questions, and only the first is answered by a brochure. That makes viscosity the input you bring to the conversation.

Describe the product as you actually make it — how it flows, whether it holds shape, whether it is abrasive. Then ask the supplier to name the pump type they propose and why it suits that behaviour.

The source does not publish a viscosity range for tube fillers, so the supplier's reasoning, not a number on a datasheet, is what you are evaluating. If two shortlisted machines differ only in pump type, the deciding evidence is a trial on your product, not a comparison of substrate lists.

Price your SKU mix against changeover scope

Changeover time scales with how much of the format you are changing. Stored recipes plus quick-release tooling are reported to cut it substantially¹⁷.

That means your SKU mix, not the machine's headline speed, sets what format range really costs you. The figures below are one publisher's reported times for tube machines.

Ask each supplier to quote against the same four scopes so the numbers are comparable.

Match the compliance regime to your product category

The regime that applies depends on whether your tube product is a pharmaceutical or a cosmetic. An audit will ask the supplier to evidence the features that regime expects, rather than accept a generic readiness claim.

Finished-pharmaceutical cGMP is codified in 21 CFR Parts 210/211². For cosmetic lines, one peer source cites servo piston dosing, 316L contact surfaces, validated CIP/SIP, PLC recipe management, integrated checkweigher and vision.

It also cites ATEX components for solvent products, with IQ/OQ/PQ aligned to ISO 22716 and EU 1223/2009²⁵. That source is describing bottle filling lines, so treat the feature list as a prompt for what to ask, not as a tube-machine specification.

• ✓Confirm whether your product is regulated as a drug (21 CFR 210/211) or a cosmetic (ISO 22716 / EU 1223/2009) and state it in the RFQ
• ✓Ask for the product-contact material grade and supporting documentation for wetted parts
• ✓Ask whether CIP/SIP is offered and request the validated cleaning parameters in writing
• ✓Request PLC recipe management and electronic batch records if batch traceability is required
• ✓Ask for IQ/OQ/PQ documentation scope and who executes it
• ✓If the product contains solvents, ask which components are ATEX-rated
• ✓Ask the supplier to list the certifications the machine actually holds, with certificate numbers

Make throughput and dosing tolerance a trial obligation

No source in this set states a tubes-per-minute output or a dosing tolerance for tube filling machines. So a rated maximum is not evidence you can plan against.

Procurement guidance for packaging machinery is to send an identical RFQ to every shortlisted supplier and evaluate total cost of ownership rather than machine price. It also advises requiring documented output on your actual product rather than the manufacturer's rated maximum^9,14.

Put that obligation into the RFQ as acceptance criteria.

• ✓Require a timed run on your tube and product, with output recorded in tubes per minute
• ✓Ask for the fill-weight or fill-volume spread from that run, stated as the supplier's measured result
• ✓Specify the tube diameter and fill volume the trial must use, and require the same conditions from every bidder
• ✓Ask what the quoted output assumes for tube diameter, product viscosity and configuration
• ✓Require the trial report to state reject rate and the cause of rejects
• ✓Ask how the machine is integrated with your existing line equipment and controls

Compare offers on total cost of ownership, not machine price

Machine price is the smallest part of the comparison you can actually make. Generic procurement guidance for packaging machinery advises a total cost of ownership breakdown rather than machine price alone.

It also warns against treating price as the primary decision factor¹⁴. Confirm spare-parts availability and service response times before you commit¹⁴.

Budget lines that are easy to miss include installation, training and maintenance. Warranty and after-sales support are named as cost factors in their own right⁸.

No source in this set gives a tube filling machine price, tooling cost, warranty term or lead time. So each of these has to come back from the supplier as a stated line item in the same format from every bidder.

When the quotes return, the comparison that holds up is the one where every supplier answered the same questions in the same units.

What to confirm before you order
