How extrusion moulding creates clear solutions for packaging and display

We thought today we’d take a few moments to explain the benefits of VisiPak, which is a division of Sinclair & Rush.

The manufacturing of clear plastic tubing, boxes and clamshells has been taken to an art form by our parent company in the States who have pushed extrusion moulding to its limits. We will also be adding this manufacturing method to our existing Dip Moulding and Injection Moulding operations in Kent.


How does extrusion moulding work? An extruder consists of a hopper for feeding in the raw materials. It has a heating section where the materials are melted into the desired consistency and a section for transferring the melted solution through a die after which it is cooled to create the finished product. Each section can be manipulated by many variables to create different thicknesses and finishes of the plastic product.

How does one process create so many different end products? This is all down to the design of the die. The different dies create the different sizes, shapes, thicknesses and finishes, tailoring the materials to the application and spec. One machine can easily be used for different products by swapping the die.


S&R have an extensive line of clear plastic packaging tubes and tubular containers together with probably the largest line of cap & plug options.

Packaging tubes range from sealed bottom containers (Permaseal - see image below) to hanging tubes to heavy-duty industrial packages while our stock line of clear plastic mailing tubes is unrivaled in the industry in terms of quality, price, and selection. Plus, as the largest manufacturer of vinyl tube caps in the world, VisiPak gives you the broadest selection of caps at unbeatable prices.


These are suitable for packaging toys, cutting tools, posters, welding rods, cosmetics, bath salts, beads, and virtually anything else you can imagine. Ideal for keeping items safe in storage or by post and perfect for point of sale (POS) display.

A benefit of thermoformed packaging is being able to shape a package to your product.  Visipak produces clamshells, blisters and trays to protect and display your products.  With extensive design flexibility and our low-cost tooling thermoformed packages are an ideal fit for many applications.


Production of transparent boxes is made to order.   These clear folding cartons are available in a variety of shapes and styles including sleeves to protect a package and inserts to separate contents inside the box.  You'll choose from a number of materials and decorating options to meet your specific needs.
