PLA plastic bags

PLA plastic bags are biodegradable plastic bags made from plant starch. They have the following characteristics:

Advantages:

Biodegradable: PLA plastic bags can be decomposed by microorganisms in the natural environment, ultimately converting to water and carbon dioxide, and will not pollute the environment. High transparency: PLA plastic bags have high transparency, which can well display the contents inside the bag.

Non-toxic: PLA plastic bags do not contain hazardous substances and will not harm human health.

Disadvantages:

High price: Due to high production costs, PLA plastic bags are much more expensive than traditional plastic bags.

Poor heat resistance: PLA plastic bags are not heat-resistant and may deform if left in a high-temperature environment for a long time.

PBAT plastic bags

PBAT plastic bags are biodegradable plastic bags made from a blend of PE and PBAT. They have the following characteristics:

Advantages:

Biodegradable: PBAT plastic bags can be decomposed by microorganisms in the natural environment, with a relatively short degradation time, and will not pollute the environment. Soft: PBAT plastic bags are relatively soft and not easy to break. Non-toxic: PBAT plastic bags do not contain hazardous substances and will not harm human health. Disadvantages:

High price: Due to high production costs, PBAT plastic bags are much more expensive than traditional plastic bags. Poor heat resistance: PBAT plastic bags are not heat-resistant and may deform if left in a high-temperature environment for a long time.

Starch-based plastic bags

Starch-based plastic bags are plastic bags made primarily of starch, with the addition of certain plasticizers and degradants. They have the following characteristics:

Advantages:

Biodegradable: Starch-based plastic bags can be decomposed by microorganisms in the natural environment, with a relatively short degradation time, and will not pollute the environment. Relatively low price: As starch is a common raw material, starch-based plastic bags are relatively inexpensive. High transparency: Starch-based plastic bags have high transparency, which can well display the contents inside the bag.

Disadvantages:

Poor durability: Starch-based plastic bags have poor durability and are prone to tearing. Poor heat resistance: Starch-based plastic bags are not heat-resistant and may deform if left in a high-temperature environment for a long time.

Biobased polylactic acid plastic bag:

Biobased polylactic acid plastic bags are biodegradable plastic bags produced through fermentation processes using corn starch as raw material. They have the following advantages:

Advantages:

Biodegradable: Biobased polylactic acid plastic bags can be decomposed by microorganisms in natural environments, and the degradation time is relatively short, which will not cause pollution to the environment. Durable: Biobased polylactic acid plastic bags are relatively tough and not easily broken. Recyclable: Biobased polylactic acid plastic bags can be recycled and converted into fertilizers or used to produce new plastic through biodegradation.

Disadvantages:  

Higher price: Due to higher production costs, biobased polylactic acid plastic bags are more expensive than traditional plastic bags. Poor heat resistance: Biobased polylactic acid plastic bags are not heat resistant and may deform if placed in a high-temperature environment for an extended period.

PVA water-soluble bag:

PVA water-soluble bag is an environmentally friendly plastic bag that is soluble in water and made from polyvinyl alcohol (PVA). PVA is a biodegradable material that can quickly decompose in natural environments, eventually converting into carbon dioxide and water. The advantages of PVA water-soluble bags include:

Advantages:

Biodegradable: PVA water-soluble bags can quickly degrade in natural environments, with minimal impact on the environment and without causing pollution. Strong solubility: PVA water-soluble bags have strong solubility in water, and only require a certain amount of time to dissolve completely, making it very convenient. Safe and hygienic: The materials used in PVA water-soluble bags will not cause pollution to the contents of the bag, making them safe and hygienic to use.

Disadvantages:

Poor durability: PVA water-soluble bags are not as durable as traditional plastic bags and are easily broken. Higher price: Due to higher production costs, PVA water-soluble bags are more expensive than traditional plastic bags.
