Application
Due to its good processability. The grade has a low energy consumption during processing
and has a good draw down ability.This grade enables high speed production of film without
blocking.The material is very suitable for thin industrial film,thin packaging film and carrier
bags which require high toughness in combination with high resistance to tearing ,good
optical properties and excellent converting properties.
General information
LPC produces low density polyethylene by the tubular reactor process. As a result the product
range covers a wide variety of densities and melt flow rates. The LDPE grade slate has a wide
variety of slip and anti block additives levels and includes a large numbers of grades with
excellent optical properties. LPC tubular production technology guarantees a very low gel level
and outstanding draw down ability, low odor and taste levels, which is of advantage for thin
film processing and e.g. food packaging.
Quality
LPC is fully certified in accordance with the internationally accepted quality standard ISO
9001-2000.It is LPC policy to supplymaterials that meet customers specifications and needs
and to keep up its reputation as a pre eminent, reliable supplier of e.g. polyethylene.
Environment
The environmental aspects of any packaging material do not only imply waste issues but have
to be considered in relation with the use of natural resources, the preservations of foodstuffs,
etc.LPC considers polyethylene to be an environmentally efficient packaging material. Its low
specific energy consumption and insignificant emissions to air and water designate
polyethylene as the ecological alternative in comparison with the traditional packaging
materials.
Recycling
Recycling of packaging materials is supported by LPC whenever ecological and social benefits
are achieved and where a social infrastructure for selective collecting and sorting of packaging
is fostered.Whenever ‘thermal’ recycling of packagings (i.e. incineration with energy
recovery)is carried out, polyethylene –with its fairly simple molecular structure and low
amount of additives-is considered to be a trouble-free fuel.
Food approvals
The converter/food packager is responsible for compliance of the performance of the final
article under foreseeable conditions of use. More specific information on the regulatory aspects
of the LPC polyethylene is available in the relevant Food Approval Declarations which can be
obtained from LPC Sales Office..
Safety
Under normal conditions polyethylenes do not present a toxic hazard through skin contact or
inhalation. During processing contact with molten polymer and inhalation of volatilized fumes
should be avoided. It is recommended to install exhaust hoods over processing machines and
to keep working area well ventilated. More specific information on the safety aspects of the
LPC polyethylenes are provided in the relevant Material Safety Data Sheets, available from
LPC Sales Office.
Storage
As polyethylenes ,like most polymers, are combustible ,the usual precautions concerning
ignition sources should be taken in warehouses and storage rooms. where large quantities are
kept in store, it is necessary to observe the normal rules for orderly stock control and to keep
out dust and moisture. Polyethylenes should be stored in such a way as to prevent exposure to
direct sunlight, as this may lead to quality deterioration.
