Definitions
- the present invention relates to hydroxy compounds in plastic packaging.
- hydroxy compounds are often transferred to the manufacturer, especially in prilled or scaly form, when smaller quantities up to a few tons to be transported or stored.
- the prills or scales are typically offered as bagged goods.
- a disadvantage of this form is the elaborate production of prills or scales using flake tapes and rollers or prilling devices, as well as the fact that clumped or melted product can only be removed from the packaging incomplete.
- hydroxy compounds having a melting point at standard pressure of 20 to 90 0 C includes all compounds having at least one hydroxy group, which meet the aforementioned melting point condition. Of these, for example, oligomeric or polymeric carboxylic acid esters having hydroxy end groups are included.
- material containing hydroxy compounds also includes mixtures containing one or more hydroxy compounds.
- Preferred solidified materials containing hydroxy compounds in a plastic package containing polyethylene or polypropylene are those in which the solidified material contains the hydroxy compounds to 90 to 100, preferably 95 to 100 and particularly preferably 98 to 100 wt%.
- Preferred hydroxy compounds having a melting point at standard pressure of 20 to 90 0 C are primary, secondary or tertiary mono-, di-, tri- and polyalcohols having a melting point at standard pressure of 20 0 C to 90 0 C, preferably 24 ° C to 72 ° C.
- Particularly preferred hydroxy compounds are oligomeric reaction products of 1, ⁇ -dicarboxylic acids, such as, for example, adipic acid with 1, ⁇ -dialcohols, such as, for example, 1,6-hexanediol, provided they contain terminal hydroxyl groups and the hydroxy compounds indicated in the table below:
- Very particularly preferred hydroxy compounds are hexane-1,6-diol and trimethylolpropane.
- the production of solidified material containing hydroxy compounds in a plastic package containing polyethylene or polypropylene, for example, can be such that the material containing hydroxy compounds
- the pouring is carried out with the greatest possible exclusion of air or under protective gas.
- the term should solidify or solidify that the material is not frozen during its filling, but is liquid or is present as a flowable mass.
- solidified materials are understood to be those which have a viscosity of more than 10,000,000 mPa ⁇ s, preferably more than 50,000,000 mPa ⁇ s, at 20 ° C.
- Preferred plastic packages containing polyethylene or polypropylene are films or tubes containing polyethylene or polypropylene, which are welded into open sacks prior to pouring or open sacks containing polyethylene or polypropylene.
- the films, tubes or bags have a wall thickness of 0.020 to 1 mm, more preferably 0.1 to 0.25 mm and are for packaging quantities of 5 to 50 kg, preferably 20 to 30 kg, particularly preferably 20 to 25 kg of solidified
- the weight ratio of packaging to solidified material is, for example, 1: 2000 to 1:50, preferably 1: 500 to 1: 100.
- the plastic packages preferably have handle or retaining holes. In this way, the emptying of the solidified material through better fixation is still further eased. Also, the plastic packaging may contain conventional predetermined breaking or - Soll abolishonne, Aufr Regard Huawein or corresponding markings that facilitate opening of the plastic packaging.
- plastic packagings are those which contain at least 95% by weight of polyethylene (LDPE, HDPE), polypropylene (PP, or prestretched or directed types such as OPP, BOPP) or mixtures thereof in the product-contacting layer.
- LDPE polyethylene
- PP polypropylene
- OPP OPP
- BOPP prestretched or directed types such as OPP, BOPP
- the plastic packages themselves filled with the solidified material may in turn be surrounded by secondary packaging such as cardboard boxes, drums, containers or in the usual way on pallets e.g. be wrapped by another protective film.
- Another particular advantage is that the weight ratio of plastic packaging to solidified material can be very low.
