Film Property Range Aspects

Sealing Range 75-145° C Improves Productivity

Seal Strength 250 – 1200 gms Improves Productivity

Hot Tack 150 -400 Gms. Improves Productivity

WVTR <0.3 gms/Sq m/day Improves Self Life

OTR < 1 cc/sq m/day Improves Self Life

Density 0.55 -0.95 gms/cc Improves Yield

Shrinkage 1-10 % Print Registration & Tight Wrap

Heat Resistance High To absorb abuse on Packaging Line

Visual Appearance Gloss , High – Low Silk Matt, Pearl, White

WVTR:- Water Vapor Transmission Rate

OTR:- Oxygen Transmission Test

BOPP

Technical Trends – Materials.

• High purity resins

• Tailor made crystallinity with support from Process and Catalyst Chains.

• Wider variety and more sophisticated masterbatches.

BOPP FILM

DEMANDS FROM PROCESSOR OF BOPP FILM:

• Continuous running at high speeds

• Capability of producing lower thickness

• High Filter life

• Maximum one break per day.

BOPP FILM

MARKET DEMANDS – TECHNICAL• Good Opticals – High gloss & low haze

• Good Mechanicals, Stiffness

• Low Shrinkage

• Retention of Surface treatment

• Low ash content in Capacitor films

• Ease of Metallization and crack resistance

• Meeting targeted MVTR & OTR

Role of Additives - Antiblock

• Functions :- It will facilitate the extrusion process and handling of the finished goods by reducing the problems of materials sticking to each others.

• Types Of Antiblock:- 1) Organic 2) Inorganic .

• Grades Available :-

SR. NO. Grade Active Ingredient % LDR %

1 ANTIBLOCK AB051CP 5 % Silica 2-3 %

2 ANTIBLOCK AB06CP 5 % Organic Antiblock

3 SLIP & ANTIBLOCK (BOPP)

Role of Slip Additives- BOPP

• Function:- Used for enhance the smoothness of film by reducing the tackiness of polymer and bring out reduced COF. These are Migratory on surface and forming lubricating layer on the film.

• Characteristics:- 1) work as a Internal Slip Agent.

2) Reduced COF.

3)Increase Throughput.

4) Reduced Film to film adhesion.

• Grades Available:-

Sr. No Grade Active Ingredient % LDR %

1 SLIP (BOPP) MB 04 6 % Slip Additives

Role of Antistatic Additives- BOPP

• Functions:- Polyolifines are by nature possess the electrical

insulation properties which gives them the potential to built up the high static charge due to frictional heat or hot air. Antisat contains the organic molecules which are incompatible with polymer and hence it migrates on the surface, it provides conducting path to dissipate the electric charge.

• Characteristics:- 1) Reduced surface resistivity.

2) Reduced Dust pickup.

3) Reduced static charge.

4) Surface Resistivity 10 E10 to 10 E 12 ohms.

• Grades Available :-

Sr. No Grades Active Ingredient % LDR %

1 ANTISTATIC BOPP MB 04 12.5 % 1.5- 2.5 %

2 SLIP & ANTISTATIC MB 5 % Antistatic & 10 % Slip 1-3 %

Role of Antioxidants Additives- BOPP

• Functions:- These are high performance antioxidants design to improve the processabiltiy , reduce thermal degradation during melt processing and when plastic are subjected to high temperature.

• Characteristics:- 1) Reduced thermal degradation during polymer processing.

2) Reduced Imbrittlement of Plastic.

3) Gel Minimization.

4) Prevent Yellowing of plastics.
