Different thicknesses, colors, and sizes of trash bags come into our daily lives. Why are there different types of them to manufacture? This post can offer you answers.
First of all, let’s overview all sorts of trash bags.
Different Types of Trash Bags
According to the sizes and capacity, there are small trash bags and large heavy-duty trash bags.
- Small trash bags:
Small trash bags are designed to fit the little bins. They can generally collect and load between 2 to 5 gallons of waste and are suitable for collecting and disposing of food waste, paper, and other small items. The smaller bags are just used as daily garbage bins and become indispensable.
- Large heavy-duty trash bags:
Large heavy-duty trash bags are produced to carry heavier waste. The larger one is the first choice when you need to load a heavy-duty item. They can typically hold between 30 to 40 gallons, with thicker ones having greater capacity. When you encounter a lot of heavy kitchen waste, this larger garbage bag comes in handy.
From the perspective of use scenarios, garbage bags can be divided into kitchen trash bags, car rear seat trash bags, lawn and leaf bags, and contractor bags.
- Kitchen trash bags:
Kitchen garbage bags are large enough to carry those leftovers from the diet with water, oil, or soup. In addition to the characteristics of needing a large enough capacity, they also need to be strong and durable to prevent punctures and leaks.
- Car rear seat trash bags
Car rear seat garbage bags are mainly used to collect and store waste in the car, which makes the environment in the car cleaner and tidier. When you need to travel by car, car garbage bags are even more necessary. Using onboard garbage bags is not only more hygienic but also allows the driver to focus more on driving and not be distracted by other items in the car.
- Lawn and leaf bags:
Lawn and leaf bags are designed to hold waste generated after gardening work, such as branches, blades of grass, and withered flowers. These bags are relatively large and can withstand heavy-duty gardening waste.
- Contractor bags
Compared to standard garbage bag products, contractor bags are larger and stronger. Therefore, they are highly praised when used to hold heavy-duty waste. The construction industry uses the most common option for collecting waste such as rotors, tiles, steel bars, etc.
According to the final degradability, plastic trash bags can be divided into traditional non-degradable bags, biodegradable bags, and compostable bags.
- Traditional non-degradable trash bags:
These bags are made from polymers, most of which are extracted from petroleum. The more common are polyethylene(PE), polypropylene(PP), and polyvinyl chloride(PVC). They are widely used, but they also cause white pollution because they are discarded indiscriminately.
- Biodegradable trash bags:
Biodegradable pouches are made from traditional plastic material plus degradable substances. These degradable substances include corn starch, cellulose, degradation additives, etc. These types of bags can degrade into water, carbon dioxide, and other biomass under specific conditions. They are environmentally friendly and versatile and have become an emerging hot product in the market.
Compostable bags are similar to biodegradable bags but specifically designed for composting conditions. These bags can give the soil a wealth of organic matter after composting. These garbage bags also cover extensive applications, for food waste bags, garden waste, and so on.
In conclusion, garbage bags come in different sizes and types. We can choose the right garbage bag according to the characteristics of the waste and the different occasions.
Reasons for Different Styles
Various styles are perhaps determined by the resin raw materials, or thickness and sealing devices. Besides, the use of garbage bags will vary on different occasions.
The resin matter
The main raw material of plastic bin bags is synthetic resin. Synthetic resin is a polymer compound synthesized artificially and can be processed into plastic products by adding additives, or directly processed into shapes. They combine the advantages of multiple polymers to make products that present good performance. Traditional plastic garbage bags are made of resin raw materials such as polyethylene, polypropylene, and polyvinyl chloride, while biodegradable garbage bags are made of PLA, PBAT, PHA, etc. The characteristics of different resin raw materials are different, which also determines the texture of the finished bags.
Thickness
In our daily life, we often see various garbage bags of different thicknesses. The thickness of commonly used small garbage bags is generally 1.5-2.5 silk, and this thickness range of garbage bags is suitable for small garbage cans supported by individual stores, catering industries, etc. Bags with a thickness of 2.5-5 silk are commonly used in property, hotel, cleaning, sanitation, garden, and other industries, and some thickened rubbish bags are used to carry heavy items. Based on the weight requirements of the load, manufacturers will produce refuse bags of different thicknesses to meet the customer’s choice.
Sealing arrangement
Sealing types are designed to satisfy different needs of customers. There are three main categories: flat seal bags, star seal bags, and gusset seal bags.
With flat mouths and flat bottoms, flat-seal bags are suitable for small trash cans to hold lightweight items. This kind of bag requires people to lift by hand and tie their mouths, and then throw them into a large trash can, which is very inconvenient.
The star seal bag is a type of bag with a multi-pointed star at the bottom. This sealing design is to prevent the refuse bags from sliding into the bottom of the trash can as soon as the garbage is placed in the bag.
The gusset is a triangular shape formed when the corners of a flat bag are folded and sealed. Because this gusset is folded, it enhances the bearing capacity of the corner of the bag.
The application scenarios
There are generally several colors of bags in trash cans in public places: green, blue, and gray. The different colors are meant to distinguish different garbage. Green represents kitchen waste, blue represents recyclable materials, and gray represents other general waste. Color differentiation of different garbage is conducive to garbage sorting and reduces the trouble of garbage disposal in the later stage.
For household use, different styles are depending on the characteristics of waste. Bags used in kitchens need to be thicker, stronger, and leak-proof. For general food waste and small items in the living room, a small bag is enough. For construction waste, contractor bags must be on the field.
Conclusion
In a word, different trash bags are determined by raw materials. As life needs change, more and more bags with different thicknesses, colors, and sealing properties are designed. Nowadays, we can choose the most ideal garbage bag according to our needs and use occasions.
