What does it all actually mean? We want to do educational work. In our “Schröder Wiki” you will find many explanations and explanations of terms from the packaging industry.
Did you not find something or is something still unclear to you?
Then give us a call, we will be happy to answer any questions you may have.
Biopolymers are made from renewable raw materials and are the basic building blocks for the production of compostable packaging.
Disposal in your own garden.
The term "Industrial Compostable" refers to large industrial composting facilities that specialize in industrial composting. Items advertised as "Industrial Compostable" can be disposed of in such specialized composting facilities.
Post-consumer recyclables are wastes that are disposed of in the yellow bag or PET bottles generated by consumers (individuals, households, offices...).
PIR
Post-industrial recycling is waste that is generated, for example, during the production process in industry.
Polyethylene is the chemical name for the most commonly used plastic in the world.
Eco-label for particularly environmentally friendly products and services. The holder of the label is the German Federal Ministry for the Environment.
PLA is a transparent plastic that is very similar to LDPE. PLA consists of lactic acid molecules and is industrially compostable.
Cellulose base is the material from which some biodegradable products such as glassine paper are made. Cellulose base is a collective term for fibers(pulp fibers) . The fibers are mostly obtained from cotton and linen.
DIN CERTO is a certification company of the TÜV Rheinland Group and the certification body for issuing DIN marks. DIN CERTO is an independent company that is allowed to issue standards in almost any industry. It is also accredited or recognized in the legally regulated area by independent domestic and foreign bodies.
Jute is an annual plant belonging to the genus Corchorus. The two varieties Corchorus capsularis and Corchorus olitorius contribute largely to fiber production.
Plants produce organic material from light and water with the help of their chloroplasts.
CO2 is a mixture of oxygen and carbon. Chemically it is defined as non-toxic, water-soluble, colorless and odorless.
Renewable raw materials Renewable raw materials are organic substances from agriculture and forestry. (corn, potatoes, sugar cane and grass).
Oxo-degradable or oxo-degradable plastics are also often incorrectly referred to as bioplastics. In the case of oxo films, a wide variety of substances are added to conventional films and, under the influence of light, heat and oxygen, this material breaks down into the smallest pieces. The plastic does not decompose completely, microplastics are created.
Shrink films are films that are ideal for packaging products airtight. The film is usually used as a half tube and is stretched over the product to be packaged. Once the product is wrapped, a machine or heat can cause the film to contract and lie skin tight against the product, protecting it from scratches, dust and other influences. The shrink films differ in different shrink strengths, FFS (high shrinkage) and FFY (low shrinkage).
The term "downsizing" is often associated with the automotive industry. There it describes the reduction of the engine displacement or the gasoline consumption with the same performance. This also works in the same way for our products. With our Eco-Light products we implement this, through the optimized production one saves raw materials with Eco-Light at constant quality. Thus, the environment is protected and the consumer of the packaging continues to have his usual product.
The TÜV Austria GROUP is an economically and politically independent certification body. The purpose of the company and the related organizational and operational structure is purely focused on the performance of certifications.
The compostable bio-shrink film is made of NA6 material, which is based on vegetable starch and PLA.
The petrochemical recycling into naphtha-like cracker precursors ultimately leads to the production of ethylene and propylene and thus back to new plastics. The cycle would thus be closed, and this could be the future royal road.
Polymer to monomer The depolymerization of plastics to their monomers has no significance for used plastic packaging made from polyolefins. They cannot be converted to their monomers ethylene or propylene on a large scale. PET, as a counter-example, can be converted to the monomers ethylene glycol and terephthalic acid with the aid of methanol. This is worthwhile for colored bottles that can no longer be used in the bottle-to-bottle process.
The pyrolysis of PE/PP/PS fractions in the "Tacoil" process takes place, for example, at temperatures of approx. 450 to 700 °C in the stirred tank. The flakes enter the boiler via an extruder at 250 to 300 °C. The flakes are then fed into the reactor. Above the reactor is a condenser in which long-chain fragments condense out and then run back into the boiler. Only the desired shorter chains remain in the gas phase and are fed first to an atmospheric distillation and in the second step to a vacuum distillation. Products are diesel, kerosene and light oil.
Plastics can thus be dissolved in solvents, polyolefins for example in decalin or polystyrene in toluene. This technology is suitable, for example, for the processing of PE/PA composite films.
Cellulose is the main component of plant cell walls. Cellulose is used as a raw material for paper production and in the chemical industry, as well as in other areas.
Glassine is a largely greaseproof, but not wet-strengthened, transparent paper. It is used for window envelopes, kite paper or as packaging for confectionery.
The Erema recycling plant can regranulate film up to 100%, which means that the film returns to the original raw material.
