Plastic Blow Moulding Technique: An Overview

  Blow Moulding is a manufacturing process used to produce hollow plastic parts by inflating a heated plastic tube until it takes the shape of a Mould cavity. This method is particularly effective for creating products with consistent wall thickness and complex shapes. Developed in the mid-20th century, blow Moulding has become an integral part of many industries, including automotive, packaging, and agriculture. In agriculture, the process has seen significant advancements and is used for making various products, such as containers for pesticides, irrigation equipment, and even large tanks. This blog will explore the blow Moulding technique, its current practices, applications in agriculture, and future perspectives.     Blow Moulding Technique: Process and Variants   The blow Moulding process involves several steps:   1.        Parison Formation: A plastic tube, called a parison, is extruded. The parison is then pl...

Advantages and Disadvantages of Bioplastic

 

Advantages and Disadvantages of Bioplastic

 

Introduction

Bio plastic industry is growing very fast, it is estimated that it by 2024 it production will grow from 1.5 million tons to 2..4 Million ton. Demand in bioplastic is growing. Despite the demand its use in 1% as compared to crude based plastic.

BioPlastic specialty

Bioplastics are generally.

1.       These are plant based  and organic

2.       Compostable, Biodegradable

3.       Recycling is easy.

4.       Can make allied product with Crude oil based platic. Compatible with oil based plastic.

Advantages of Bio-Plastic

1.   Use of crude oil plastic will be reduced so that micro plastic formation will reduce which was causing harm to environment.

2.     Bioplastic have same property as synthetic plastic so that they can also perform injection molding and will produce same product . Some cased bioplastic is more stronger and light weight.

3.  Bioplastic will cause less impact on environment. It will biodegrade naturally and can be compostable.

4.   Many bioplastic are naturally occurring and will not produce CO2. They don’t have any carbon foot print.

5.  Common bioplastics, such as starch-based PLA and PHB, are non-toxic and of ‘no health concern’. 

6.       Their usage may improve the value-add of a product through a green marketing campaign.

Disadvantages of bioplastics

1.   Expensive: - Bio plastic is more expensive than any convention synthetic plastic like Polyethylene and PET. They are 2 to 3 times more expensive.

2.  Large Area: - Bio Plastic requires large area for cultivation. These are terrestrial crop, that may cause food supply issues. Industry requires almost 3% of cultivation land for production bioplastic.

3.     Short Life:-  Bioplastic have shorter life span as compared with convention synthetic Plastic. E.g. some algae based bioplastic breaks down in water in just an hour.

4.  Disposable: - Being compostable, bioplastic requires specific procedure to dispose those bio plastic wastes. It requires large area for land filling bio plastic.

5.  General Fit: - These bio plastic are fit for certain applications only and very bad for other applications.

6.       Processing Cost:- Bio Plastic  processing requires very costly procedures.

Ecofriendly Bioplastic Short Note

In recent years, there has been a growing concern over the negative impact of plastics on the environment. Traditional plastics can take hundreds of years to decompose, and they are a major contributor to pollution, litter, and waste. One solution that has gained popularity is the use of biodegradable plastics. Biodegradable plastics are made from natural materials that can break down quickly and safely in the environment. These materials include corn starch, sugarcane, and other plant-based sources. Unlike traditional plastics, which are made from petroleum, biodegradable plastics do not contain harmful chemicals that can leach into the soil or water. One of the main benefits of biodegradable plastics is that they reduce the amount of waste in the environment. Since they can break down quickly, they do not accumulate in landfills or pollute waterways. This is especially important for marine ecosystems, where plastic waste can harm marine life and disrupt the food chain. Another ben...
