Plastics and packaging production lines in South Africa, scenario by scenario: injection, blow, bag, pipe, recycling and paper

Who this is for

Moulders, converters, recyclers and packaging start-ups in South Africa, and the manufacturers who want to bring their own packaging in-house. It reads across our plastics and paper price guides so you can find your row and go to the page that prices it.

The conditions that apply to every plastics and packaging line

The scenarios, one by one

Scenario 1: a first injection moulding shop

A 150–300 tonne machine at US$30–75k, servo control adding 10–15%, with auxiliaries, a chiller and the first moulds on top. Tonnage follows the part, not the ambition, and the mould budget is the line most often missing. Injection moulding machine prices and tonnage guide matches parts to tonnage and prices the auxiliaries.

The mould budget is the line most often missing from a first enquiry, and it is not a rounding error. A machine runs any mould that fits its platen and tonnage; a mould runs one product and carries the cycle time, the wall thickness and the surface finish that decide whether the part sells. Two shops with the same machine and different moulds are not in the same business.

Auxiliaries are the second omission. A moulding machine needs chilled water, dry material and a way of handling regrind; without them the cycle lengthens, rejects climb, and the saving on a cheaper machine is spent within a year on scrap. Servo control earns its 10–15 per cent here on the electricity bill alone, and it cuts the heat the chiller has to remove as well.

Scenario 2: crates, pallets and large parts

Crates, pallets and large housings need 400–500 tonne machines from US$100k and above, larger moulds and heavier cooling. The tonnage guide sets out the step and what changes in the shop when the machine gets heavier.

Going from 150–300 tonne to 400–500 tonne changes the building, not only the machine. Heavier clamp forces need a floor that takes the load, a crane or forklift that can change a mould now weighing tonnes, and a chiller sized for a much larger shot. Shops that plan only the machine find the mould change is a half-day job they cannot staff.

Crates and pallets also have a different commercial shape. The parts are bulky and cheap per kilogram, so the delivery radius is short and the customer is industrial rather than retail. Offtake contracts, not machine capacity, are the thing to settle first.

Scenario 3: PET preforms and bottles

A preform operation is an injection machine at US$30–75k plus a preform mould set that is often the same size of investment, and a blow moulder to turn preforms into bottles. We do not publish a stand-alone preform machine band because the mould decides the number. Plastic bag, pipe and preform machine prices explains the components; the PET versus glass versus can guide covers the bottling side.

We do not publish a stand-alone preform band because a preform operation is three purchases pretending to be one: the injection machine, the preform mould, and the blow moulder. The mould is specified by neck finish, preform weight and cavity count — and cavity count is what sets output, so two quotations for “a preform machine” can differ fourfold in what they actually produce.

For a water plant the first question is whether to make preforms at all. Buying preforms and blowing on site needs less capital and keeps bottle design flexible; making preforms pays once volume is high and steady enough to keep the moulds busy, and it adds resin buying, drying and quality control to a business that was previously filling water.

Scenario 4: a bag-making shop

Basic bag-making machines start at US$8k and reach US$40k and above with full servo control; film supply, printing and the bag specification decide the business. The bag, pipe and preform guide gives the tiers.

Film supply and printing are what separate a shop from a converter. A basic machine makes a plain bag; a servo machine with print units makes a branded one, which is where the margin sits and where setup time, ink and plate costs arrive. The step is worth taking only if the customers who pay for print exist inside the delivery radius.

Extended producer responsibility belongs in the plan rather than in the compliance file. A producer of packaging carries registration and reporting obligations here, and the fee follows the material and the tonnage placed on the market — which means the bag specification is a cost decision as well as a technical one. Settle it before the machine, not after the first return is due.

Scenario 5: pipe and profile extrusion

A single-screw pipe line starts at US$20k; multi-layer co-extrusion runs to US$200k and above, and the die set and the downstream haul-off and cutter decide the output as much as the extruder. Pipe carries a product standard the buyer will test against, and the line must be specified to make it.

The extruder gets the headline and the downstream sets the output. A single-screw line will run faster than a haul-off and cutter can take away, so the die set, the calibration and cooling tank and the cutter decide metres per hour and wall consistency. Buyers who specify only screw diameter end up limited somewhere they did not quote.

Pipe carries a product standard, and that standard is tested on the pipe rather than on the machine. Pressure class, wall thickness and marking have to be held batch after batch, which makes raw-material consistency and process control part of the specification — and makes multi-layer co-extrusion a material-cost decision as much as a technical one.

Scenario 6: PET and film recycling

A PET recycling wash line is US$120–350k across the 300–1,000 kg per hour range, and the plant is a bale-supply business first: without collection contracts the line starves. Wash water and effluent need a permitted route. Plastic recycling machine prices sets out the wash line, pelletising and film options.

A recycling line is a collection business with machinery attached. The wash line is the visible capital; the survival factor is bale supply under contract, because a line sized for 1,000 kilograms an hour and fed 400 loses money on the difference every shift. Secure the bales before the plant, not after.

Water and effluent are the second constraint and the one most often under-planned. A wash line uses water in volume and returns it dirty, so treatment and recirculation belong in the project from the start — both because the authority will ask and because buying that water twice is a running cost nobody quotes.

Scenario 7: toilet paper and tissue converting

A converting line, buying jumbo rolls and producing finished rolls, starts at US$10–50k for entry and manual configurations and reaches the US$1M class fully automatic; making the paper itself is a different plant and the guide draws that boundary. Toilet paper, tissue and egg tray machine prices covers both.

Converting and making are two different industries sharing a word. A converting line buys jumbo rolls and turns them into finished product: light, cheap to enter, limited by jumbo supply and by delivery. Making the paper is a mill — pulping, a paper machine, energy and water at industrial scale — and it is not an extension of a converting business.

Within converting, the span from US$10–50k to the US$1M class is automation and finished-product quality rather than throughput alone. Entry configurations need hands at every station; the automatic class handles logs, wrapping and packing, and it is bought when labour, consistency and the retail pack specification justify it.

Scenario 8: egg trays and moulded pulp

Forming machines from US$8k in the 1,000–3,000 pieces per hour class, and a small complete plant with pulping and drying at about US$30k for roughly 20,000 trays a day. Waste paper supply and drying energy are the operating cost lines.

Egg trays are a drying business. The forming machine is cheap; the operating cost is the energy used to take moulded pulp from wet to stackable, and the margin follows the dryer more than the former. A small complete plant at about US$30k for roughly 20,000 trays a day is priced accordingly, and it lives or dies on the cost of that heat.

The feedstock is the other half. Waste paper supply is local, variable in quality and price, and it decides both the tray strength and the reject rate. Trays are also bulky and cheap, so the delivery radius is short — which makes the local paper supply and the local customer the same geographic question.

Scenario 9: recovering an old injection or extrusion line

Old machines with dead controllers and worn screws are often a control retrofit at US$2–8k per machine plus a screw and barrel set, and a measurement layer that shows whether the constraint is the machine or the mould change. The plastics OEE retrofit case study shows the measurement step; when to upgrade your PLC and new, used or recover cover the decision.

A control retrofit plus a screw and barrel set is the highest-return move available to an existing shop, and it is routinely skipped because it is unglamorous. The frame, the clamp and the platens are usually sound; what has expired is the electronics and the screw geometry. At US$2–8k per machine for the control, plus the screw set, the machine comes back able to hold a recipe — which is what the new machine was being bought for.

Measure before you spend. A measurement layer shows whether the constraint is cycle time, changeover or material drying, and the answer is often drying or changeover rather than machine capacity. That answer costs a fraction of a new machine to act on, and it produces the evidence a funder or a board wants before approving capital.

Scenario 10: in-house packaging for a manufacturer, or a tender-driven project

A food or chemical manufacturer bringing bottles or bags in-house is scenario 3 or 4 with a captive customer, and the decision turns on volume and mould ownership. Where the buyer scores local content, mould making and frame fabrication are the elements that can be done locally; see local content scoring and China versus local fabrication. Packaging lines also carry inspection requirements that machine vision answers at a known cost.

Bringing packaging in-house is scenario 3 or 4 with a captive customer, and the arithmetic is different because the demand is already known. The decision turns on volume and on mould ownership: a manufacturer who owns the mould controls the design and the second-source option; one who does not is buying a part, not a capability.

Where a tender or a corporate supply chain applies local-content scoring, decide the scope split element by element before the order. The scope that scores is the fabricated, installed and engineered portion, which is also the portion best built here; our B-BBEE and local content page sets out how that split moves the score.

The map on one table

Bands are indicative USD, 2026, on the basis stated in each row; they are the same bands our price guides publish, so the row and the guide always agree. Machinery is priced in US dollars and the rand cost moves with the exchange rate.

What CISH does with your row

The feasibility call starts from the part or the pack, confirms tonnage or line class, prices the whole project including moulds, cooling and material stock, and hands you a written scope. Delivery is the same for every row: turnkey lines commissioned to an agreed output on your material and moulds, operators trained during run-up, documentation handed over.
