LDPE T-Shirt Bags for Sweet Potatoes

LDPE T-Shirt Bags for Sweet Potatoes | High-Strength Flexible Produce Packaging Solutions

Rizhao Luming Plastic Technology Co., Ltd. manufactures LDPE T-Shirt Bags for Sweet Potatoes engineered specifically for agricultural supply chains. Operating from a 16,500 m² production facility with 120+ skilled employees and 100+ sets of advanced equipment, the company delivers hundreds of millions of vegetable packaging bags monthly. These specialized bags feature virgin low‑density polyethylene construction with integrated vest handles, providing puncture resistance and flexibility ideal for irregular tuberous produce. Each bag is manufactured using mature film‑blowing and heat‑sealing technology developed through years of vegetable packaging expertise. The LDPE T‑Shirt Bags achieve excellent clarity for product visibility while maintaining robust load‑bearing capacity up to 15 pounds per unit.

Material Properties for Agricultural Applications

Low‑density polyethylene provides exceptional elongation rates between 400‑600%, allowing your bags to stretch under heavy loads without failure. This flexibility becomes critical when handling rough‑textured sweet potatoes with protruding ends.

The material maintains its ductility even in cold storage environments. Unlike brittle alternatives, these bags resist cracking during refrigerated transport and cold chain logistics.

High optical clarity enables immediate quality inspection at retail points. Your customers can evaluate produce freshness without opening packaging, reducing product waste and improving purchasing decisions.

Virgin LDPE resin ensures food‑safe direct contact compliance with FDA 21 CFR 177.1520 standards. You receive packaging that meets international food safety regulations without compromise.

Our well‑optimized production workflow guarantees consistent batch quality for every LDPE T-Shirt Bags for Sweet Potatoes, whether you place small trial orders or large‑volume monthly shipments for farm and retail distribution.

Technical Specifications

Engineered Ventilation for Extended Shelf Life

Strategically placed micro‑perforations facilitate controlled airflow throughout your packaged LDPE T-Shirt Bags for Sweet Potatoes produce. This engineered ventilation balances internal humidity levels, preventing condensation buildup that accelerates spoilage.

The perforation design manages ethylene gas accumulation naturally released by sweet potatoes during respiration. By allowing gas exchange, your produce maintains optimal freshness from pack-house to consumer.

Ventilation holes are precisely cut to prevent tear initiation points. Quality inspection ensures clean edges that maintain structural integrity while providing necessary air circulation.

This breathable design extends marketable shelf life by reducing anaerobic conditions. Your sweet potatoes stay fresher longer, decreasing shrinkage losses and improving customer satisfaction.

Versatile Applications Across the Supply Chain

At high-volume retail self-service areas, these bags dispense easily from roll formats for bulk bin operations. The high coefficient of friction ensures effortless opening for your customers while handles support heavy selections.

Industrial pack-houses utilize these bags on automated bagging lines where LDPE flexibility accommodates high-speed filling without tearing. Your production efficiency increases through reliable mechanical handling performance.

During cold chain export logistics, the material maintains flexibility despite refrigerated container temperatures. Your packaged produce withstands vibration and stacking pressures throughout long-distance shipping.

Farm-gate processing operations benefit from the bags' ability to protect irregular-shaped produce during initial handling. The puncture resistance prevents failures when loading freshly harvested sweet potatoes with soil residue.

Rigorous Quality Control Standards

Dart impact testing following ASTM D1709 protocols simulates real-world dropping scenarios during filling operations. Each production batch undergoes evaluation to ensure consistent impact resistance.

Tensile strength verification confirms that vest handles withstand sustained vertical loads without stretching to failure points. Your customers experience reliable carrying performance throughout transportation.

Ultrasonic thickness gauging across film webs identifies any thin spots before production completion. This prevents weak areas that could compromise puncture resistance during use.

Food-grade compliance testing verifies virgin resin purity and migration limits. You receive documentation confirming regulatory compliance for direct food contact applications in your target markets.

Customization and Branding Opportunities

Corona discharge surface treatment ensures excellent ink adhesion for flexographic printing. Your farm branding, nutritional information, and product traceability codes reproduce with clarity across up to eight colors.

Custom size configurations accommodate different packaging volumes from small retail portions to bulk commercial quantities. The production facility adapts bag dimensions to match your specific handling requirements.

Color options extend beyond standard transparent film to include tinted variations for brand differentiation. Your packaging stands out on retail shelves while maintaining product visibility.

Handle reinforcement specifications adjust according to your typical load weights. The engineering team configures handle thickness and width to match your distribution demands.

Frequently Asked Questions

Q：Why use LDPE instead of HDPE for sweet potatoes?
A： LDPE offers significantly higher puncture resistance and flexibility essential for irregular shapes and rough textures. Sweet potatoes would easily puncture thinner, more brittle HDPE alternatives during handling.

Q：How do these bags prevent sweet potatoes from sweating and rotting?
A： Engineered micro-perforations or punched vent holes facilitate airflow, balancing internal humidity and preventing ethylene gas and condensation buildup that accelerates decay.

Q：What is the maximum weight capacity for a standard LDPE T-Shirt bag?
A： Depending on micron thickness, a standard 12x7x22 inch bag typically handles 5lbs to 15lbs (approximately 2.2kg to 6.8kg) of produce safely.

Q：Are these bags recyclable in standard streams?
A： Yes, LDPE carries Recycling Code #4 and is widely accepted in plastic film recycling programs, supporting your sustainability and circular economy initiatives.

Q：Can the bags be customized with branding?
A： Absolutely. Corona-treated LDPE surfaces ensure high ink adhesion for flexographic printing up to 8 colors, accommodating complex nutritional labeling and farm branding requirements.

Packaging and Delivery

Bags are packaged in master cartons with moisture-resistant liners to protect film quality during storage and transit. Standard packaging quantities range from 500 to 2,000 units per carton depending on bag size specifications.

Cartons are palletized according to container loading optimization standards. Stretch wrap secures pallet loads for stable transportation across international shipping routes.
