However, the three most important factors that have great influence on the performance of polyethylene greenhouse films are weather parameters, stabilization of plastics, and chemical treatment. The effect of these parameters are discussed in detail in the following sections. [Pg.190]

Among recent developments in HALS from Great Lakes Chemical is a tertiary amine HALS, Uvasil 816, offering better performance (including better resistance to pesticides) in applications such as polyethylene greenhouse film. New BZTs include Lowilite 5 5, for processing at high temperatures, and Lowilite 94 for PP, with food-contact approval. [Pg.114]

Plastics have achieved a dominant position in agriculture and horticulture over the past twenty years, which has merited the new description plasticulture. This is in part due to the replacement of glass in greenhouses and tunnels by polyethylene, but more particularly in the development of polyethylene mulcK. Polyethylene for greenhouse films...

In this paragraph, the results of the above discussed systems are compared with those for a blend obtained by adding 50% of recycled polyethylene, RPE, to the PLC mixture. RPE is mainly composed of low density polyethylene coming from recycling of greenhouse films. This new system has been investigated considering the results already obtained for similar compositions. ... [Pg.109]

Considering polyethylenes tested in these blends, LDPE and polyethylene recycled from greenhouse films gave the best results. [Pg.98]

Useability of a transparent polyethylene film in hotbeds and greenhouses is obvious, since this film, as opposed to glass, displays high light permeability in the ultraviolet spectral region. [Pg.76]

As cast or blown films we encounter polyethylene in packaging films, bags, cling film, greenhouse skins, diaper back sheets, and high altitude scientific balloons. In these applications... [Pg.299]

Consequently, the running costs plus interest charges are lower than that for glass greenhouses. Some black polyethylene film is used directly in contact with the soil, with holes cut for plants. Attempts have been made to make such films biodegradable, so that they can be ploughed in at the end of each growing season. [Pg.309]
