10 Scenarios – Shipping Bags vs Cardboard Boxes
Scenario 1: Shipping a T-Shirt
|
Detail
|
Information
|
|---|---|
|
Product
|
Cotton t-shirt, folded, weight 200g
|
|
Fragility
|
Not fragile
|
|
Customer expectation
|
Basic packaging is fine
|
|
Recommendation
|
Shipping Bag (Poly Mailer)
|
|
Why
|
T-shirts are soft, lightweight, and not breakable. A poly mailer protects against moisture and dust while keeping shipping costs low.
|
Scenario 2: Shipping a Wine Glass
|
Detail
|
Information
|
|---|---|
|
Product
|
One wine glass, weight 150g, fragile
|
|
Fragility
|
Very fragile
|
|
Customer expectation
|
Expects careful packaging
|
|
Recommendation
|
Cardboard Box + Bubble Wrap
|
|
Why
|
A shipping bag will not protect a wine glass from crushing or impact. The glass needs a rigid box and cushioning material (bubble wrap, foam, or paper).
|
Scenario 3: Shipping a Hoodie
|
Detail
|
Information
|
|---|---|
|
Product
|
Heavy cotton hoodie, weight 800g
|
|
Fragility
|
Not fragile
|
|
Customer expectation
|
Basic packaging is fine
|
|
Recommendation
|
Shipping Bag
|
|
Why
|
Hoodies are soft and flexible. A thick poly mailer or woven poly bag provides enough protection while keeping weight low.
|
Scenario 4: Shipping a Laptop
|
Detail
|
Information
|
|---|---|
|
Product
|
Laptop in original box, weight 2.5kg, high value (S$1,500)
|
|
Fragility
|
Fragile
|
|
Customer expectation
|
Expects secure, protective packaging
|
|
Recommendation
|
Cardboard Box + Padding
|
|
Why
|
A laptop is high-value and sensitive to impact. The original box needs protection inside a larger outer box with padding (air pillows, foam, or paper). Never ship electronics in a bag.
|
Scenario 5: Shipping a Book
|
Detail
|
Information
|
|---|---|
|
Product
|
Paperback book, weight 400g
|
|
Fragility
|
Moderate (corners can bend)
|
|
Customer expectation
|
Book should arrive without bent corners
|
|
Recommendation
|
Shipping Bag (Bubble Mailer)
|
|
Why
|
A bubble mailer provides cushioning and protects corners. A poly mailer alone is too thin – corners may bend. A cardboard box is overkill and adds weight.
|
Scenario 6: Shipping a Set of Cosmetics
|
Detail
|
Information
|
|---|---|
|
Product
|
3 bottles of skincare products, glass bottles, weight 600g
|
|
Fragility
|
Fragile
|
|
Customer expectation
|
Expects leak-proof, secure packaging
|
|
Recommendation
|
Cardboard Box + Bubble Wrap + Leak-proof bag
|
|
Why
|
Glass bottles can break. Liquids can leak. Use bubble wrap around each bottle, place in a leak-proof plastic bag, then pack tightly in a cardboard box.
|
Scenario 7: Shipping a Plush Toy
|
Detail
|
Information
|
|---|---|
|
Product
|
Soft plush toy (teddy bear), weight 300g
|
|
Fragility
|
Not fragile
|
|
Customer expectation
|
Basic packaging is fine
|
|
Recommendation
|
Shipping Bag (Poly Mailer)
|
|
Why
|
Plush toys are soft, flexible, and unbreakable. A poly mailer is perfect – lightweight, waterproof, and cheap.
|
Scenario 8: Shipping a Ceramic Mug
|
Detail
|
Information
|
|---|---|
|
Product
|
Ceramic coffee mug, weight 350g
|
|
Fragility
|
Fragile
|
|
Expects mug to arrive intact
|
Basic packaging is fine
|
|
Recommendation
|
Cardboard Box + Bubble Wrap or Paper
|
|
Why
|
A mug is fragile but not extremely delicate. Wrap in 2-3 layers of bubble wrap, place in a snug cardboard box with minimal empty space. A shipping bag offers no crush protection.
|
Scenario 9: Shipping a Bag of Rice (5kg)
|
Detail
|
Information
|
|---|---|
|
Product
|
5kg bag of rice, heavy, puncture risk
|
|
Fragility
|
Not fragile
|
|
Expects mug to arrive intact
|
Expects bag to arrive without ripping
|
|
Recommendation
|
Shipping Bag (Woven Polypropylene Bag)
|
|
Why
|
A heavy-duty woven PP bag (like rice sack material) is perfect. It is strong, tear-resistant, and can hold 5-25kg. Cardboard boxes are also an option but may tear under heavy weight.
|
Scenario 10: Shipping a Subscription Box (Mixed Items)
|
Detail
|
Information
|
|---|---|
|
Product
|
Monthly subscription box – snacks, small items, samples, weight 1.5kg
|
|
Fragility
|
Mixed (some snacks can crush)
|
|
Expects mug to arrive intact
|
Expects nice presentation (unboxing experience)
|
|
Recommendation
|
Cardboard Box
|
|
Why
|
Subscription boxes need a rigid container to protect the contents. A branded cardboard box creates a premium unboxing experience. Shipping bags crush easily and look less professional.
