What to Use Instead of Plastic Bags

With increasing environmental concerns and tightening regulations, businesses are under pressure to move away from traditional plastic bags. Viable alternatives include biodegradable options¹, reusable materials², and recyclable paper.

Reusable bags (such as canvas or PP non-woven), biodegradable materials like PLA³, and recyclable paper⁴ bags are currently the most effective substitutes for traditional plastic. BagMec® manufactures the specialized machinery required to produce these sustainable options.

The global phase-out of single-use plastics represents a permanent market shift. Consumers now expect brands to demonstrate environmental responsibility. A company’s choice of bag can reflect its values, and selecting the right alternative depends on product type, brand positioning, and customer expectations.

Switching to sustainable options can involve new production challenges. Biodegradable films, for instance, may be more sensitive to heat. Reusable bags require reinforced handles to ensure durability. Each material demands specific manufacturing techniques, and BagMec® designs machines to meet these requirements for a smooth transition.

Are Biodegradable Bags Better for the Environment?

"Biodegradable" suggests an eco-friendly solution, but its effectiveness depends on proper disposal.

Biodegradable bags, particularly those made from PLA, offer environmental advantages—but only if disposed of correctly in industrial composting⁵ facilities. Without this, their benefits are significantly reduced.

Types of Biodegradable Materials

Different biodegradable materials behave differently and require unique handling:

• PLA (Polylactic Acid): Made from renewable sources like corn starch, with characteristics similar to plastic. Requires specific tension and heat settings during manufacturing.
• PHA⁶ (Polyhydroxyalkanoate): Produced by microorganisms, it degrades in a variety of environments but is currently costlier.
• Starch-Based Plastics: Often blended materials that break down more easily. Suitable for applications like single-use garbage bags.

Disposal Infrastructure Matters

Most biodegradable bags need high heat and microbial activity—only available in industrial composting facilities—to degrade properly. In landfills, they can break down slowly and release methane. Effective use of these materials requires not only better products but also better public waste systems.

Biodegradable vs. Traditional Plastic: A Comparison

Feature	Biodegradable Bags (PLA)	Traditional Plastic Bags (PE)
Raw Material Source	Renewable (corn, sugarcane)	Fossil Fuels (oil, gas)
Production Energy	Lower	Higher
Carbon Footprint	Lower overall	Higher overall
End-of-Life	Industrial Composting	Landfill or Ocean
Breakdown Time	Months (with composting)	Centuries

BagMec®’s Role in the Transition

BagMec® assists clients in adapting to biodegradable materials. For instance, when US Eco-Brand aimed to produce fully compostable shopping bags, BagMec® modified a T-Shirt Bag Machine with a Smart Tension Control system to handle delicate PLA film, enabling high-quality, large-scale production.

Reusable Shopping Bags and Their Market Impact

Reusable bags have reshaped consumer habits and created opportunities for brand differentiation.

They reduce reliance on single-use plastics, offer a profitable product line for retailers, and serve as effective branding tools.

From Disposable to Durable

The shift to reusable bags reflects changing consumer priorities. Customers now accept—and often prefer—paying for bags that can be used multiple times. This opens markets for durable, branded products and new manufacturing opportunities.

Many producers now operate both high-speed T-shirt bag machines and Loop Handle Bag Machines to serve different segments.

Material and Design Options

Reusable bags require diverse materials and flexible manufacturing:

• PP Non-Woven⁷: Affordable, durable, and easy to print. Ultrasonic welding provides strong handle attachment.
• Canvas and Cotton: Natural, appealing materials used by premium or eco-conscious brands.
• Laminated Films: Used for cold food or insulated bags. Multi-layer construction handled by lamination pouch machines.

Economic Considerations

Reusable bags cost more per unit but offer different business benefits:

Aspect	Single-Use Plastic	Reusable Bags
Cost per Unit	~$0.02	~$0.50
Distribution	Free, adds cost	Sold, adds revenue
Branding	Minimal	High visibility
Customer Loyalty	Neutral	Enhances loyalty

Precision in Manufacturing

Producing durable reusable bags requires reliable machinery. The Loop Handle Bag Making Machine⁸ (priced $33,000–$38,000) is designed for high-speed, automated production with reinforced handle attachment and consistent sealing.

How Businesses Can Choose the Right Eco-Friendly Bag

Selecting the appropriate eco-friendly bag⁹ involves balancing cost, performance, brand goals, and sustainability.

Businesses must assess their product requirements, branding goals, and customer expectations before choosing between paper, PLA, or reusable materials².

Step 1: Define Your Needs

Key questions to consider:

• What are you packaging? Heavy or perishable items may require stronger or food-grade bags.
• Who is your customer? Are they cost-focused or sustainability-driven?
• What’s your brand image? Natural brands may prefer paper; modern brands may choose sleek reusable bags.
• What laws apply? Regional regulations can restrict certain materials or bag types.

Step 2: Match Needs to Materials and Machines

BagMec® offers tailored solutions across sectors:

Retail

• Need: Cost-effective, branded bags.
• Options: Reusable loop or patch handle, or biodegradable T-shirt bags.
• Machines: Loop Handle Machine or Patch Handle Machine ($8,500–$15,500). T-Shirt Bag Machine ($17,000–$32,000) for biodegradable films.

Food Packaging

• Need: Hygienic, sealable packaging.
• Options: Laminated pouches, side-seal, or FFS bags.
• Machines: FFS Machine ($34,000–$48,000) or Wicketer Bread Bag Machine ($69,000–$88,000).

Industrial/E-commerce
