Frequently Asked Questions

Polyethylene is a plastic and is divided into different types: PE-HD (HDPE): high density polyethylene (0.94 – 0.97 g/cm³); the polymer chains are weakly branched together PE-MD (MDPE): medium den...

Uniform branches with only a few short side chains with a density between 0.87 g/cm³ and 0.93 g/cm³ ("LLD" stands for "linear low density") It is a soft polyethylene that is produced under high press...

Strongly branched polymer chains, therefore low density between 0.915 g/cm³ and 0.935 g/cm³ ("LD" stands for "low density") It's a soft polyethylene. which is produced under high pressure. This is th...

Packaging material marked "food safe" or "suitable for food" may be used in direct contact with food without health concerns.Furthermore, neither the taste nor the smell of the food should be affected...

In general, all PE types are not resistant to UV rays. Exceptions to this are the black-colored types, which are resistant to UV rays, also in conjunction with atmospheric oxygen. During the polymeri...

Most plastics have an electrical surface resistance of >1015 ohms and are therefore electrostatically chargeable. The consequences are: dust attraction and sparking. Antistatic additives can reduce...

The barrier properties of polyethylene mean no or very little permeability of gases (e.g. oxygen), vapors (e.g. water vapour) and aromas. Depending on the film thickness, the following values result: ...

The water vapor permeability of plastic films is a basic property of film packaging. Especially in the packaging area, e.g. to protect dry products from moisture or to prevent moist products from dryi...

Low density between 0.895 g/cm³ and 0.920 g/cm³. Produced by the polymerization of propene. The upper service temperature is 100°C to 110°C. Chemically, PP is relatively similar to PE, but significant...

Average density between 0.930 g/cm³ and 0.940 g/cm³. The melting point is 125 to 128°C. Temperature resistant from -50°C to +90C. Created by mixing LDPE and HDPE, combining the properties of LDPE and ...

Plastics (polymers) can be divided into three classes according to the structure-property principle: thermoplastics (which can be reshaped at higher temperatures), duroplastics (hard, crystalline plas...

In order to determine the dimensions of a shrink hood or box hood, it is important to calculate the optimal height. How are the dimensions determined correctly? Since material is lost through the si...

Weakly branched polymer chains, therefore low density between 0.940 g/cm³ and 0.970 g/cm³ ("HD" stands for "high density"). Matt surface; high strength at low strengths, crackling/rustling effect. Gre...

Yes, polyethylene is easy recyclable. In Germany almost all plastics are collected, sorted and recycled via the dual system. Polyethylene has the largest share of recycled plastics, followed by polypr...

As a plastic packaging buyer, you've probably noticed the skyrocketing price increases and raw material shortages. Since the year 2000, the prices for polyethylene, the basic material for LDPE, MDPE a...

Most plastics have an electrical surface resistance of >1015 ohms and are therefore electrostatically chargeable. This can lead to dust attraction and sparking. By using antistatic Masterbachtes, t...

rLDPE is sorted, reprocessed production waste. Only LDPE foils are used unclaspated and without any additives. Waste from LDPE production is processed into new recyclate in our in-house regeneration ...

Material resistance The material resistance of LDPE and PP is not as high as that of HDPE due to the higher density. LDPE is resistant to water, diluted acids, alkalis, solutions of inorganic substan...

The term masterbatch or color granules refers to plastic additives in the form of granules. They are also called "polymer-bound additives". The density is higher than pure LDPE granules. They are adde...

Despite all the electronic production monitoring tools, minor deviations cannot be avoided. These are often caused by external temperature fluctuations during extrusion. The permitted tolerances and ...

As a manufacturer and supplier of plastic packaging, we are very aware of our responsibility when it comes to sustainability and environmental protection.We are constantly looking for sustainable alte...
