Question 1

What is a courier bag used for?

Accepted Answer

A courier bag (also called a poly mailer) is a lightweight, tamper-evident plastic packaging bag used to ship non-fragile items like clothing, accessories, documents, and small goods. It replaces cardboard boxes for soft or semi-rigid products, reducing shipping weight and cost.

Question 2

What is the difference between a courier bag and a poly mailer?

Accepted Answer

They are generally the same product - courier bag is the more common term in Indian e-commerce, while poly mailer is used more globally. Both refer to a self-sealing plastic shipping envelope made from LDPE or HDPE.

Question 3

Are courier bags waterproof?

Accepted Answer

Yes. Courier bags made from polyethylene (LDPE/HDPE) are inherently waterproof and resistant to moisture, protecting contents from rain and humidity during transit.

Question 4

What materials are courier bags made from?

Accepted Answer

Most Indian courier bags are made from LDPE (low-density polyethylene) or HDPE (high-density polyethylene). Biodegradable alternatives use PBAT (polybutylene adipate terephthalate) blends for compostable options.

Question 5

What size courier bag do I need for my product?

Accepted Answer

It depends on your product category: 6x8 inch for small accessories/jewelry, 8x10 to 10x12 inch for standard clothing items, 12x16 inch and above for bulkier apparel or multi-item orders. Order samples across sizes before committing to bulk.

Question 6

What micron thickness should I choose for courier bags?

Accepted Answer

For lightweight items (single garments, accessories), 51-micron bags are standard. For heavier or higher-value items, 60-micron or above provides extra puncture and tear resistance. Higher micron means a stronger bag, which is especially important for reducing RTO caused by damaged packaging.

Question 7

Can I get custom branded courier bags?

Accepted Answer

Yes, most suppliers including Pethiyan offer custom printing with your logo, brand colours, and return address. Custom printing typically requires a higher MOQ than plain bags - confirm with your supplier before ordering.

Question 8

What is the minimum order quantity for courier bags?

Accepted Answer

MOQs vary widely by supplier, from 100 pieces up to 1 lakh pieces for some manufacturers requiring custom printing runs. Always confirm plain vs printed MOQ separately, as printed bags typically require significantly higher minimums.

Question 9

Do courier bags ship pan-India?

Accepted Answer

Yes, most established suppliers including Pethiyan deliver pan-India with standard delivery times of 3-5 business days for in-stock sizes.

Question 10

How are courier bags packed for delivery to me?

Accepted Answer

Courier bags are typically shipped in bulk cartons or rolls depending on quantity ordered. Bulk orders of 10,000+ pieces are usually palletised for freight shipping.

Question 11

Can I track my courier bag order?

Accepted Answer

Yes, tracking information should be provided by your supplier once the order is dispatched - confirm this is standard practice before ordering from any new supplier.

Question 12

What is LDPE and why is it used for courier bags?

Accepted Answer

LDPE (Low-Density Polyethylene) is a flexible, tear-resistant plastic that is lightweight, waterproof, and cost-effective, making it the most common material for courier bags in Indian e-commerce.

Question 13

What is HDPE and how is it different from LDPE for courier bags?

Accepted Answer

HDPE (High-Density Polyethylene) is stiffer and stronger than LDPE, offering better puncture resistance. Some premium courier bags use HDPE for high-value or heavier shipments.

Question 14

Are courier bags recyclable?

Accepted Answer

LDPE and HDPE (Grades #4 and #2) are technically recyclable, but require access to plastic film recycling streams, which are limited in most Indian municipalities. Biodegradable and compostable PBAT-based bags are a better environmental option where available.

Question 15

What does virgin quality mean for courier bags?

Accepted Answer

Virgin quality refers to plastic made from new, unrecycled polymer resin rather than recycled plastic. Virgin material typically offers more consistent thickness, clarity, and seal strength than recycled-content bags.

Question 16

Can courier bags be used to ship food products?

Accepted Answer

Standard courier bags are not designed for direct food contact - they are for outer shipping protection only. If shipping food items, use food-grade primary packaging inside the courier bag as outer protection.

Question 17

Are courier bags safe for shipping cosmetics and skincare?

Accepted Answer

Yes, courier bags are commonly used as outer shipping protection for cosmetics and skincare products, provided the primary packaging is properly sealed. The courier bag protects against moisture, tampering, and transit damage.

Question 18

How should I store courier bags before use?

Accepted Answer

Store in a cool, dry place away from direct sunlight. Prolonged UV exposure can degrade LDPE/HDPE over time, weakening seal strength.

Question 19

How do I seal a tamper-proof courier bag correctly?

Accepted Answer

Remove the protective strip from the adhesive flap, fold the bag closed, and press firmly along the entire seal length. A properly sealed tamper-proof bag cannot be reopened without visible damage to the seal - this is the security feature.

Question 20

Can courier bags be reused?

Accepted Answer

Tamper-proof courier bags are designed for single use - once sealed and opened, the tamper-evident strip is compromised and the bag should not be reused for shipping, though it can be repurposed for storage.

Question 21

What is a POD jacket on a courier bag?

Accepted Answer

A POD (Proof of Delivery) jacket is a small transparent pouch attached to the courier bag, used to insert a waybill or shipping label document that couriers can scan without opening the package.

Question 22

Accepted Answer

How long does custom printed courier bag production take?

Accepted Answer

Typical production timelines for custom printed courier bags range from 7-15 business days depending on order volume and design complexity - always confirm current lead times before planning inventory.

Question 27

Can I add a QR code to my courier bags?

Accepted Answer

Yes, QR code printing for tracking, brand links, or marketplace compliance like Meesho's QR requirement can typically be added during the custom printing process.

Question 28

What is the minimum order quantity for plain unprinted courier bags?

Accepted Answer

Plain courier bags typically have lower MOQs than printed ones - Pethiyan's current MOQ is 100 pieces per variant.

Question 29

How fast can I get courier bags delivered for an urgent order?

Accepted Answer

For in-stock plain bags, standard delivery is 3-5 business days pan-India. Custom printed orders require production lead time in addition to shipping.

Question 30

What should Meesho, Flipkart, and Amazon sellers know about courier bag compliance in 2026?

Accepted Answer

India's Plastic Waste Management Rules restrict plastic carry bags below 120 microns, with enforcement tightening in 2026 particularly in metro areas. E-commerce platforms are also adding sustainability scoring to seller profiles. Sellers should confirm their courier bags meet current micron requirements and consider biodegradable options where volume and cost allow.
