FAQ

  • How does Hyplast guarantee the quality of its products?

    The raw materials we buy are analyzed upon arrival to see if they meet the required specifications.
    During production, the consistency of the manufacturing process is monitored by means of a SPC system (statistical process control). This system involves the use of statistical techniques to measure and analyze the variation in processes.
    SPC is used to maintain the consistency of how the product is made and, therefore, of the manufactured product itself and its as-designed reliability and quality.
    A primary tool used for SPC is the control chart, a graphical representation of certain descriptive statistics for specific quantitative measurements of the manufacturing process. These descriptive statistics are displayed in the control chart in comparison to their "in-control" sampling distributions. The comparison detects any unusual variation in the manufacturing process, which could indicate a problem with the process.
    Furthermore, film samples are taken during production and checked in our lab. Some tests are carried out by the operators themselves e.g. dart drop measurement, microscopics (layer distribution), tear resistance, reflection (colouring), determination of sealing behaviour of the film…
    In this way the quality of our products is always guaranteed.

  • What is Hyplast's production capacity?

    35.000 tons/year

  • What is polyethylene?

    Polyethylene is the basic ingredient used in our plant to produce plastic films. Polyethylene is a plastic polymer resulting from the polymerisation of ethylene (C2H4). Polyethylene is the most popular plastic in the world. It is probably the polymer you see most in daily life. This is the polymer that makes grocery bags, shampoo bottles, children's toys, and even bullet proof vests. For such a versatile material, it has a very simple structure, the simplest of all commercial polymers. A molecule of polyethylene is nothing more than a long chain of carbon atoms, with two hydrogen atoms attached to each carbon atom. Polyethylene is defined by its grade (hot fluidity) and density (weight/volume), e.g. Low density polyethylene (LDPE); Linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), High density polyethylene (HDPE).
    * A polymer is a type of molecule that takes the form of a long chain. The word polymer comes from two Greek words, poly meaning many and mer meaning parts. So, as het name implies, polymers are made of many parts, called monomers or monomeric units, that are chained together.
    * Ethylene is obtained by heating naphtha very intensely (“cracking”).
    * Naphtha is another word for petroleum. You get naphtha from crude oil.

  • How does Hyplast turn polyethylene granulate into plastic film?

    The process used at Hyplast is blown film extrusion. The polyethylene granules are brought into a machine (extruder) with cylinder via a tunnel and are then heated. Inside this cylinder, a rotating screw pushes the melted mass forward. The melted material is blown through the opening of a mould with compressed air and then rises like a tube of film. After cooling, the rollers flatten the film into a double layer, after which it is rolled up and is ready for further processing. The film can consist of one layer (mono-extrusion) or multi layers (co-extrusion). At Hyplast, we can produce films of 7 layers.

  • How does Hyplast determine their product prices?

    Our policy is to offer products with an excellent price/quality ratio.
    For Hyplast, quality is a top issue. Our priority is to guarantee the quality of our products. Just like in every business, prices are determined by several elements like: market supply and demand, availability and prices of raw materials and additives, and other costs like manufacturing, transport, packaging….
    Hyplast always maintains honest prices in harmony with the product quality.

  • Why does Hyplast ask you to order minimum quantities?

    To keep the price of our products reduced, it is important to produce in an economical way, maintaining large production runs with as less switches as possible.

  • Where can I buy Hyplast films?

    Hyplast supplies plastic films all over the world using many distribution channels: distributors, commercial agents, and representatives.

  • Does Hyplast have any registered tradenames?

    Yes, Hyplast has several registered tradenames: Hermetix, Rhino Silo, Hyflex, Hytec…

  • How long can I use my plastic film?

    There are a lot of elements having a negative influence on the lifetime of a film, e.g.:

    • Exposure to sunlight accelerates degradation of the film. In order to prolong the lifetime of a film UV-stabilisers and UV-absorbers are joint to the raw materials. These additives neutralize the negative effects of the UV-light in a way that the lifetime of the film can be extended to a certain point.
    • Use of pesticides: pesticides, especially sulphur and chlorine, containing ‘reacting agents’ can have a very negative influence on the lifetime of a film. The use of specific protective additives help to control these influences. Nevertheless, the use of pesticides in combination with PE films has to be avoided as much as possible, as pesticides will accelerate aging of the film when used in high concentrations.
  • In what ways films can be folded?

    There are many ways that we can finish our products: e.g.
    unfolded, double-folded, U-folded, with or without gussets, and with or without slit on either one side or both sides or in the middle.
    This all depends on the width of the film, the demands of the customer, and the machinery used for the specific quality.

  • How does Hyplast determine delivery times?

    Our standard products can normally be delivered from stock. Custom-made products have to be inserted into the production planning. Our planning department tries to combine different production orders in the best possible way in function of orders specifications, the availability of the necessary machines, raw materials, other materials and operating people.

  • Are plastics harmful for the environment?

    From an environmental point of view, polyethylene is one of the friendliest materials. After all:

    • It is an economical raw material. For the world production of polyethylene, not even 1 percent of the total production of crude oil and natural gas is used annually.
    • The production of polyethylene is relatively clean and efficient: the emission of harmful substances is minimal and there is virtually no waste.
    • Polyethylene is extremely suitable for reuse.
      It is a thermo-plastic material, which means that it can be melted down and used for making products virtually indefinitely.
      Nowadays many carrier bags and dustbin bags are made from recycled polyethylene in this way.
    • When polyethylene is collected after use and it cannot be processed again, it supplies a high-grade fuel for the provision of energy.
  • How does Hyplast care for the environment?

    The plastic waste, produced when switching to another production run, is recycled into granulate. This is done in our recycling plant KPR. Then, the recycled material is reused at Hyplast’s plant in some of our film qualities.
