[hindi_jokes] updated VERY VERY VERY Important INFO about Water Bottle!!!

Dear Recipient,

The earlier message was a rumor. If you have circulated that please
circulate this too.

The Numbers actually denote the material that is used to make the
bottles. This is used to sort the bottles when they are recycled. The
triangle is actually recycle mark. If the bottles of different are
mixed during recycling they will produce a new kind of hybrid plastic
that may not have good enough properties (like strength) to hold the
material.

Number - Material
1      - PET
2      - HDPE
3      - PVC
4      - LDPE
5      - Polypropylene (PP)
6      - Polystyrene (PS)
7      - Other Materials

1
Polyethylene Terephthalate (PET, PETE). PET is clear, tough, and has
good gas and moisture barrier properties. This resin is commonly used
in beverage bottles and many injection-molded consumer product
containers. Cleaned, recycled PET flakes and pellets are in great
demand for spinning fiber for carpet yarns, producing fiberfill and
geo-textiles. Nickname: Polyester.

•Clear and optically smooth surfaces for oriented films and bottles
•Excellent barrier to oxygen, water, and carbon dioxide
•High impact capability and shatter resistance
•Excellent resistance to most solvents
•Capability for hot-filling

2
High Density Polyethylene (HDPE). HDPE is used to make many types of
bottles. Unpigmented bottles are translucent, have good barrier
properties and stiffness, and are well suited to packaging products
with a short shelf life such as milk. Because HDPE has good chemical
resistance, it is used for packaging many household and industrial
chemicals such as detergents and bleach. Pigmented HDPE bottles have
better stress crack resistance than unpigmented HDPE.

•Excellent resistance to most solvents
•Higher tensile strength compared to other forms of polyethylene
•Relatively stiff material with useful temperature capabilities

3
Polyvinyl Chloride (PVC, Vinyl).
In addition to its stable physical properties, PVC has good chemical
resistance, weatherability, flow characteristics and stable
electrical properties. The diverse slate of vinyl products can be
broadly divided into rigid and flexible materials.

• High impact strength, brilliant clarity, excellent processing
performance
•Resistance to grease, oil and chemicals

4
Low Density Polyethylene (LDPE).
LDPE is used predominately in film applications due to its toughness,
flexibility and relative transparency, making it popular for use in
applications where heat sealing is necessary. LDPE also is used to
manufacture some flexible lids and bottles as well as in wire and
cable applications.

Includes Linear Low Density Polyethylene (LLDPE).

•Excellent resistance to acids, bases and vegetable oils
•Toughness, flexibility and relative transparency (good combination
of properties for packaging applications requiring heat-sealing)

5
Polypropylene (PP).
PP has good chemical resistance, is strong, and has a high melting
point making it good for hot-fill liquids. This resin is found in
flexible and rigid packaging, fibers, and large molded parts for
automotive and consumer products. (Used in Yogurt / Medicine
packaging)

•Excellent optical clarity in biaxially oriented films and stretch
blow molded containers
•Low moisture vapor transmission
•Inertness toward acids, alkalis and most solvents

6
Polystyrene (PS).
PS is a versatile plastic that can be rigid or foamed. General
purpose polystyrene is clear, hard and brittle. It has a relatively
low melting point. Typical applications include protective packaging,
foodservice packaging, bottles, and food containers.
PS is often combined with rubber to make high impact polystyrene
(HIPS) which is used for packaging and durable applications requiring
toughness, but not clarity.

• Excellent moisture barrier for short shelf life products
• Excellent optical clarity in general purpose form
• Significant stiffness in both foamed and rigid forms.
• Low density and high stiffness in foamed applications
• Low thermal conductivity and excellent insulation properties

7
Other Materials

Use of this code indicates that a package is made with a resin other
than the six listed above, or is made of more than one resin and used
in a multi-layer combination.


Best regards,
Arvind Vyas.
