Description

What is Nursery Bag?

Also known as nursery bags, poly grow bags or seedling sacks, these are flexible, container bags made from quality polyethylene resin. They are known all over the world for their superior chemical resistance, mechanical properties, low water absorption, and flexibility. These bags have a wide range of uses in industrial and commercial agriculture for applications where a low weight, puncture resistant and economical material is desired.

They are especially suited for propagating in open nurseries, plant liners, propagation works, and for bulk packaging for protection in agriculture, where they are subjected to harsh environmental conditions such as continuous exposure to soil acids, chemical fertilizers, alkalis, and other agriculture additives.

Available Nursery Bag Types

Virgin Poly Nursery Bags

Produced with 100% polyethylene resin that is virgin to provide the highest seam burst thresholds, incredible structural stretch, as well as food-grade safety standards in organic saplings.

Reprocessed Industrial Sacks

Grow bags that are cost-effective and made of top-quality recycled polyolefins. Highly recommended for short-term, seasonal propagation large reforestation saplings and for secondary fields of non-critical sorting.

UV Stabilized Nursery Bags

Created with sophisticated ultraviolet chemical inhibitors, directly blended into the matrix material to prevent the film from becoming brittle or cracking during prolonged outdoor exposure to sun.

Colored & Dual-Tone Sacks

Available in various colors and dual-tone designs (such such as white outside that reflects intense solar Rays, while black inner to ward off the growth of weeds) to help visually segregate assets as well as root-protection.

Textured Anti-Slip Poly Sacks

The textured or embossed mechanically embossed outer surfaces, which provide improved friction control and prevents full sacks from falling off the pallets when transporting commercial containers.

Sizing & Volume Configuration Options

As a top nursery bag manufacturer We provide a range of volumetric cuts that can be easily integrated into automated or manual line for soil filling:

• Standards 4x8 Sheets Formats Sheets of plastic structural liner that have been pre-cut designed for the purpose of covering wooden nursery boxes as well as propagation crates.
• Custom cut seedling pouches Small, thin and bags that can be flexed for early stage seed germination as well as vertical propagation frames that save space.
• Liners for Industrial Fabrication Plants: Liner made of heavy-gauge plastic that is custom-tailored to fit metal containers for transport and large tanks for containment.
• Thick Tree Blocks that are Flexible: Thin blocks made of heavy-micron film that is designed to hold deep taproots as well as hold heavy soil weights without breaking.
• Continuous Form Sleeves for Continuous Rolls, un-slit plastic tubes that are supplied on rolls (on the request) perfect for automated, high-volume cutters for nursery use.

Nursery Bag Manufacturing Process

Singhal Industries Private Limited uses the advanced blown film extrusion systems and strictly automated quality control system to produce premium grade plant grow bags.

• Step 1: Raw Material Selection: The high grade polyethylene resins are thoroughly checked for batch density, purity indices and tensile strength values.
• Step 2: Blown Film Extrusion: The compound matrix becomes molten under high pressure and extruded through circular dies to form a continuous plastic bubble in the vertical direction.
• Step 3: Sheet and Gusset Formation: Cooling is accomplished in the bubble evenly through the use of advanced air rings, it is flattened and the gusset is formed under controlled sheet temperature conditions, which provides dimensional stability.
• Step 4: Inline Drainage Hole Punching: The poly canvas of square canopy design goes through automated die cutting punching machines to create drainage holes that do not fray.
• Step 5: Quality Testing Inspection: Every batch produced is inspected for correctness of thickness gauge, bottom seam sealing strength and passivity limits.
• Stage 6: Trimming, Packing & Dispatch: After being trimmed to precise requirements, each bag has its lower seam sealed twice, then it is packed into bulk cartons and sent out for international delivery.

FAQs (Frequently Asked Questions)

Q1: What are the principal uses of the nursery bags?

The nursery bags are soft thermoplastics that contain soil growth media and nurture seedlings, fruit saplings, ornamentals, and forest trees before final plantation.

Q2: Are the poly nursery bags heat-resistant?

Yes, the poly nursery bags have relatively decent heat resistance when compared to common commercial films, which maintain all of their shape stability and tensile strength in the extreme summer temperatures in the warehouses.

Q3: Are the polyethylene seedling grow bags resistant to chemicals?

Yes, the polyethylene grow bags have great resistance to agricultural chemical fertilizers, solvents in the composting process, organic nitrates, and acidic soil mixes, which do not decompose the plastic material.

Q4: Are the plastic bags capable of being cleanly welded and branded using corporate logos?

Yes. The polyethylene material is highly thermoplastic in nature; hence, we can easily weld the film. We can print clear-cut labels including guidelines for cropping and barcode scanning.

Q5: Are your nursery bags fully waterproof?

The pure polyolefin film has zero moisture absorption property and is fully waterproof. But then the bags come with a pre-punched drainage hole pattern to facilitate the drainage of excess water to prevent root rot.

Q6: What is the difference between the structure of poly nursery bag and fabric grow bag?

Poly nursery bags are smooth non-porous blown film sacks designed for low cost large scale manufacture and temporary seasonality transportation. Fabric grow bags are made of thick non-porous geotextiles material which allows breathing through its periphery and multiple years use.

Q7: Is it possible to make customization on length, width, gauge, etc. for bulk orders?

Yes, definitely. Being an industrial nursery bag provider, our manufacturing plants are capable of providing complete customization to enable you to design your targeted dimensions, micron specifications, colors, etc.

Q8: Can your nursery bags be recycled once they have completed their useful life?

Yes. Polyethylene belongs to pure polymer type and is 100% recyclable and can therefore be recycled to produce other useful secondary industrial plastics.

Q9: Which are the industries that commonly use your poly nursery bags?

Commercial agriculture plantations, public forestry departments, e-commerce pet and plant supply chain, chemical soil research laboratories, and general packaging industry commonly use our bags.

Q10: How do I determine the proper nursery bag thickness for my project?

It really depends on the total volume of the roots of your crops, the total soil payload weight, the aggressiveness of aggregate soil rocks, and the height of your vertical containers stacking.

Q11: Will moisture affect the film properties while storing it?

No. Our polyethylene is entirely hydrophobic; hence high levels of port humidity and/or ambient vapor exposure cannot make the bags swell, bend, rot or lose their tensile strength while storing them for a long time.

Q12: Are the bags from reprocessed materials safe for packing organic crop seedlings?

Reprocessed materials blends are very economical and suitable for trees and ornamental shrubs. However, for organic consumer crops or berry saplings, we provide 100% pure virgin resins.

Q13: Is your nursery bag film liable to become brittle when left out in the open sunlight outside?

The regular outdoor nursery bag film is manufactured using excellent UV light inhibitors that prevent any brittleness of the plastic film in the natural sunlight.

Q14: How does the low weight of these bags benefit logistics expenses?

As a result of the light density of the polymer of these heavy-duty bags ranging between 0.92 – 0.95 g/cm³, these bags will not weigh down your transportation significantly and reduce your international freight costs.

Q15: How does a business organize the export shipment of these bags from your factories?

Business-to-business procurement staff can provide us with their sizing needs, micron thickness range specifications, printing graphic files, and port of destination information so that we can provide you with factory direct prices.
