solution · line & filling

Molded fiber for automated lines and filling systems Designed for your gripper, your denester and your filling — in molded fiber

We design gripping surfaces, draft angles and stacking pitch for your line. You test prototypes on it before the production tool.

Designed to your handling data, tested on the prototype on your line — design, tool and series production from a single source.

Clarify first

Three questions before design

Handling, closing, line trial: your answers determine feasibility, budget price and schedule — for one molded part as a pilot or all molded parts on your line.

Handling

Can it be gripped and denested?

Vacuum, clamp gripper or denester: we design gripping surfaces, draft angles and stacking pitch to your handling data. We develop your shape from 100,000 units per year per molded part.

Closing

Will it run through closing and labeling?

You close bowls with heat-sealable lidding paper, and bottles and jars from the PAPACKS Model S10 with a screw cap. We design the label panel and embossing to your labeling technology.

Line trial

How do you test before the tool?

With prototypes in quantity on your system: you check denesting, gripping, filling and closing at every station and then approve the production tool. Pre-series and initial samples from the production tool also run on your line.

Molded fiber for automated lines means: molded parts and containers made of molded fiber, manufactured from virgin fiber, whose gripping surfaces, draft angles and stacking pitch are designed to the handling data of your system. You close bowls with lidding paper, and bottles and jars from the PAPACKS Model S10 with a screw cap. We supply prototypes for your line trial, build the production tool and manufacture the series. You will find the documents for your supplier approval in the download area.

Getting started

What you provide, what you receive

Your handling data is the starting point. You receive prototypes for your line trial and a molded part designed for your line.

Your information

What you provide

  • Handling data for your line: gripper type, cycle rate and stack height in the magazine
  • Manufacturer and model of your system
  • Your closing, sealing and labeling technology
  • Your product or a drawing with outer dimensions and inner contour
  • Annual volume and the date by which your molded part should be running on the line

Our deliverables

What you receive

  • Feasibility, budget price and schedule as a guide within a few days
  • The design of your molded part, engineered for gripper, denester and magazine
  • Prototypes for the line trial on your system — we set the quantity in the initial consultation based on your trial
  • The data sheet for your molded part with dimensions and tolerances; for food contact, the declaration of conformity for each molded part
  • How we share your tooling costs depends on annual volume and term — in Wet Molding, up to full coverage; the terms are set out in your quote (Custom Engineering)

From first conversation to series production

How your molded part gets onto the line

Four steps from the first question to running series production — design starts with your handling data. You give approval at three points: development after the budget quote, the production tool after the line trial, the start of production after the pre-series.

Consultation over a molded part in the development center

01

Initial consultation

You tell us handling data, system, closing technology, volume and date. You receive feasibility, budget quote and schedule as a guide — the binding quote follows after development. Within a few days.

02

Samples and examples

Sample parts from our development, matched to your project: you assess material quality, feel and appearance on a real molded part.

03

Design and prototype

Design and CAD to your handling data, prototypes in quantity for your line trial — then your approval. Around 4 weeks after the kickoff.

04

Tool and series production

Production tool made in-house, pre-series and initial samples from the production tool, then ongoing series production — stacked on pallets, delivered according to your call-off schedule. Around 12 weeks from your approval.

The times are planning estimates; they depend on your approvals, the capacity of our teams and the scope of your project. Your project team at PAPACKS presents the detailed plan around 1–2 weeks after the kickoff. You receive the process and budget quote as a guide after our initial call — with development, tool and unit price; the binding quote follows after development.

Frequently asked questions

What customers ask before the line trial

We set the tolerance according to process and geometry and confirm it in the line trial with your prototype. We clarify in the initial consultation which tolerance your gripping, denesting and loading stations need; then we choose the process. The binding tolerances of your molded part are stated in the data sheet.

Denesting depends above all on geometry: draft angle and stacking pitch determine how deep one molded part sits in the next and where it rests. We design both values for your denester and your stack height in the magazine. Bring your test results to the first meeting — stack height, cycle rate, gripper type and the station where it got stuck; with the prototype, you test denesting on your system before you approve the production tool.

Bowls and cups are closed with heat-sealable lidding paper. We source the lidding paper through our partners and select it to match your bowl; we design the sealing flange into the molded part. Sealing temperature, sealing pressure and sealing time are agreed on the prototype with your machine. Bottles and jars from the PAPACKS Model S10 carry the thread in the body and a fiber screw cap. We design the label panel to your label format; you apply your label during filling.

That depends on the contents, the humidity at the line and the cleaning process. Tell us these three factors; we then determine with you whether your molded part needs a functional coating against water vapor and oxygen (WVTR, OTR), and which one. We test on the prototype with your contents which barrier they need; the values depend on the application and are stated in the data sheet of your molded part. You check dust and abrasion at the gripper and guides on the prototype on your system.

You test prototypes in quantity on your system before the production tool is built. We determine in the initial consultation how many your trial needs, based on cycle rate, trial duration and the stations you are testing — denesting, gripping, filling, closing, labeling. In the trial, run cycle rate and magazine height the way series production will run later. We agree with you whether and how we support your trial on site. Pre-series and initial samples from the production tool also run on your line before you approve the start of production.

We develop custom molded parts from 100,000 units per year; the volume counts per molded part. Below this volume, we tell you in a consultation from what volume a dedicated tool pays off for you. We clarify in the initial consultation which process suits your line, your tolerance and your volume. The budget quote lists the costs of development, tool and unit price separately.

Your first prototypes follow around 4 weeks after the kickoff; from your approval, tool making, pre-series and start of production follow in around 12 weeks. Tell us the date by which your molded part should be running on the line: we plan the line trial and pre-series into the schedule with you, working back from that date; you decide how long your line trial takes. The times are planning estimates; they depend on your approvals, the capacity of our teams and the scope of your project.
