Sachet machinery buyer guide

Sachet Filling Machine Quotation Checklist

A useful quotation is a technical response to a defined requirement. Send every supplier the same application data and ask them to state assumptions, exclusions and acceptance criteria. The checklist below can be copied into an RFQ or user requirement specification.

Sachet Filling Machine Quotation Checklist

1. Product data

Commercial and technical product name, ingredient or material description and safety data where relevant
Liquid viscosity versus temperature, density, foaming, stringing, particles and required agitation or heating

Representative samples available for trials, with safe handling and disposal instructions

2. Dose and accuracy

Nominal dose in grams, millilitres or pieces
Minimum and maximum formats to run on the same line
Permitted upper and lower limits and the measurement method
Product temperature and density at the filler
Required checkweighing, flow monitoring or sample regime
Maximum acceptable product giveaway

3. Sachet and film specification

Finished width, length, seal style and headspace
Back seal, three-side seal, four-side seal, stick pack or premade pouch
Film laminate structure, thickness and seal layer
Reel width, maximum diameter, core, winding direction and print repeat
Registration mark, coding area, tear notch, perforation and cut profile
Finished-pack drawing and approved samples

4. Production performance

Required accepted packs per minute and annual volume
Number and duration of shifts
Expected product and format changeovers
Efficiency definition, planned stops and scrap measurement
Upstream product feed and downstream counting, conveying or cartoning
Future output or format expansion

5. Coding, inspection and control requirements

Date, batch, lot, barcode or variable-data coding
Print registration and code verification
Checkweigher, metal detector, vision or seal inspection
Reject device with reject confirmation and locked reject collection where required
Recipe management, user access, production data and communications
Emergency stops, guarding interfaces and line-control philosophy

6. Site, utilities and environment

Electrical voltage, phase, frequency and available load
Compressed-air pressure, flow and quality
Extraction, ventilation, heating, cooling, water and drainage
Room temperature, humidity, washdown, hazardous-area or clean-area constraints
Scaled layout, access route, lifting and offloading plan
Operator, maintenance and cleaning access around the line

7. Commercial and documentation scope

Machine, filler, tooling, options and integration listed separately
Delivery, insurance, offloading, positioning, installation and commissioning
Operator and maintenance training
Manuals, drawings, electrical and pneumatic information, certificates and parts lists
Recommended commissioning and two-year spares
Warranty, support response, exclusions, payment terms and validity

8. Factory and site acceptance

Define the factory acceptance test before placing the order. State the product, film, format, run duration, target accepted output, dose checks, seal tests, alarm challenges, changeover demonstrations and documentation review.

At site acceptance, confirm installation, utilities, integration, safety checks, training and production performance. Record open actions with owners and completion criteria.

Attach to the RFQ: product data, finished-pack drawing, film specification, required layout, quality-control philosophy and the proposed acceptance protocol.

Common questions

Frequently asked questions

Can this checklist be used for a budget quotation?

Yes. Mark unknown items clearly and request stated assumptions, but replace assumptions with tested data before ordering.

Should suppliers quote against the same specification?

Yes. A common requirement makes performance, scope, exclusions and lifetime cost easier to compare.

What is the most important acceptance criterion?

Accepted production output with the declared product and film is usually central, supported by dose, seal, safety, changeover and documentation checks.

RFQ control sheet

Issue one product-format matrix and one acceptance schedule

The checklist becomes more useful when it is converted into a controlled table rather than scattered emails. Each supplier should quote against the same revision and identify every assumption or exclusion.

Product reference	Product name or code, representative properties, temperature, particle or bulk-density data, hazards or compatibility information, and sample quantity available.
Dose and quality	Nominal dose, permitted tolerance, test method, sample frequency, scale or instrument responsibility and treatment of start-up or rejected packs.
Finished pack	Width, length, fill space, seal widths and pattern, corners, tear notch, perforation, strip or individual cut, code and visual acceptance.
Film or pouch	Laminate, thickness, web or pouch dimensions, reel core and winding, print repeat, eye marks, converter tolerances and approved samples.
Output definition	Accepted saleable packs over a stated period, product and format used, included refills and inspections, downstream limits and reject treatment.
Line interfaces	Product feed, conveyors, coding, inspection, reject, counting, cartoning, communications, guarding and emergency-stop boundaries.
Utilities and site	Electrical supply, compressed air, extraction, drainage, temperature, humidity, floor and access, installation hours and lifting constraints.
Documentation and support	Drawings, manuals, parts lists, software backup, test records, training, spares, warranty, service scope and language.

Require suppliers to return deviations

Ask each supplier to mark whether a requirement is included, optional, excluded or subject to trial. A clear deviation list prevents a sales summary from being mistaken for the full technical offer and makes later contract review more reliable.

Model numbers and catalogue ranges should be linked to the exact configuration, options and change parts being quoted. Avoid accepting a generic brochure as the final specification.

Attach the acceptance schedule before purchase

Define representative inputs, test duration, dose sampling, lane identification, seal and leak checks, registration, coding, rejected packs, accepted output, retained samples and run video. State which tests occur before shipment and which are repeated after installation.

Additional buyer questions

RFQ and acceptance questions

How should optional equipment be shown?

Ask for a separate description, price, technical effect and interface for each option. State whether the base machine can accept it later and what additional work would be required.

Should every sachet size be included in the RFQ?

Yes. Width, length, seal style and dose define tooling and changeover. The smallest and largest combinations are often the most important to review.

What should a supplier state about performance references?

Identify the product, dose, film, pack, lane count, speed, test duration, accepted-pack definition and conditions. Unsupported catalogue figures should remain indicative.

How can cross-domain machine options be kept clear?

Use this site for sachet and stick-pack scope, Pouch Fillers UK for broader premade pouches and Form Fill and Seal UK for broader bagging. Link to the specialist route rather than combining unlike specifications.

Define the project around your product and pack
