INTERPLEX EXPET Range of Performance APET SHEET
WHAT ARE APET SHEET ?
APET (Amorphous PET) Sheet are thermoplastic sheet which
are produced by the extrusion processing of Polyethylene Terephthalate
(APET) copolymer, a thermoplastic polyester. APET Sheet have sparkling
clarity and gloss and very good mechanical properties and thermoforming
characteristics, which make them the ideal material for packaging applications.
EXPET Range
EXPET is a range of high performance APET sheet manufactured
by Interplex India. EXPET Sheet are manufactured on imported plant utilizing
the company's long experience in the field of specialized extrusion. EXPET
Sheet have extremely good thickness tolerance, very high uniformity and
low crystallinity and excellent transparency. EXPET Sheet are made from
Reliance RELPET resins.
GENERAL CHARACTERISTICS OF APET SHEET
APET Sheet have the following general
characteristics
- Sparkling clarity and gloss which makes it visually appealing as
a material for packaging and display applications
- Very good impact strength down to a temperature of 40 oC
- High flexural modulus. This lows the possibility of down gauging
the packaging thickness while at the same time maintaining the required
properties.
- High resistance to cracking
- Does not stress whiten when flexed or bent
- Can be easily thermoformed, and does not require to be dried
- Has higher thermal diffusivity as compared to PVC (faster absorption
and dissipation of heat). This reduces the thermoforming cycle time
as the time required to heat and cool the sheet is lower. This also
requces the heating requirement and reduces energy costs
Other characteristics required for specific packaging
applications are
- Safe for food and drug contact for food and medical packaging applications
- Can be sterilized by ETO and Gamma radiation for medical packaging
- Has good barrier properties for water vapour, Oxygen and CO2 for
food packaging
- Neutral smell, and good aroma and flavour retention, for specialized
food packaging
- Non toxic and environmentally friendly, since it is a pure and does
not have halogens or harmful heavy metals, making it the ideal eco
friendly disposable packaging material
APPLICATIONS OF EXPET SHEET
Major applications of APET Sheet are in the areas of
thermoforming and packaging as follows
Blister packaging
- Pharmaceutical and medical industries - tablets, medical disposables
and medical devices for diagnostics and surgery
- Consumer goods - tooth brushes, shaving blades, battery cells
- Personal hygiene products - single use rigid pouches for hair oils,
shampoos which currently use flexible packaging
- Processed foods - single portion packing of sauces, pickles, butter
etc which are used in the catering industry
Thermoforming
- Fast foods and takeaway and beverage industry - salads, sandwiches,
ice-cream parlor cups, desserts, bakery items, mithai, tea coffee
and drinks cups
- Prepacked retail foods and confectionary - chocolate and biscuit
trays, nuts, dried fruits, mithai boxes, ice-cream, butter and cream
tubs and cups etc
- Farm Produce - boxes for strawberries and other berries, boxes and
separators for packing of high value fruit and vegetables, herbs,
egg cartons etc
- Point of purchase display packaging - electrical, electronic, tools,
toys, stationary etc
- Technical packaging - packaging and tray handling of electronic
items
Fabricated packing
- Apparel - boxes for shirts, ties, ladies hosiery
- Gift and novelty items - toys, dolls etc
- Beauty aids - scents, brushes
