販促バッグ：RPET vs. コットンキャンバス
購入特典やイベント企画では、素材選びはほぼ採算の判断です。数字を実際に動かす要素をご説明します。
RPET wins on unit cost and shipping weight at promotional volumes; cotton canvas wins when the piece needs to be kept and reused. Neither is automatically the sustainable choice — that depends on what can be documented. If the bag is the campaign rather than an add-on to it, heavier canvas is not the place to save.
Promotional programs run at volume, which means small per-unit differences compound quickly. The material choice between RPET and cotton canvas is therefore usually settled by cost per unit at the target quantity — but the two also send different signals, and that is worth weighing.
Neither is automatically the sustainable choice. That depends on what can be documented, not on which material sounds better.
数量が増えたときのコスト
RPET is lighter, which reduces both material cost and shipping weight — the second effect is easy to forget and is real at promotional volumes. It also takes print well, so the branding step does not add complexity.
Cotton canvas costs more per unit and weighs considerably more, but buys something specific: a piece the recipient is more likely to keep and reuse. For a program measured on impressions over time rather than units distributed, that changes the calculation.
それぞれが伝えるもの
RPET reads as considered and contemporary, particularly in a beauty or lifestyle context where a recycled shell aligns with the brand position. It is the safer choice when the piece accompanies a product rather than standing alone.
Heavier canvas — 12oz rather than a lighter weight — reads as durable in hand, and that is most of what separates a tote that gets reused from one that does not. If the tote is the campaign rather than an add-on to it, weight is not the place to save.
決め方
Give us the expected volume band rather than a single number when you brief. The breakpoints where one material overtakes the other are quantity-dependent, and knowing the band lets us tell you where they sit for your specific construction.
If a sustainability claim is going to appear in campaign copy, decide that at the brief stage so the documentation can be confirmed alongside the sample rather than after it.
| RPET | コットンキャンバス | |
|---|---|---|
| Unit cost at volume | Lower | Higher |
| Shipping weight | Light | Heavy — material at promotional volume |
| Perceived durability | Functional | Substantial at 12oz and above |
| Likelihood of reuse | Moderate | High |
| Best when | The bag accompanies a product | The bag is the campaign |

案件の範囲を決める段階で、この話題から実際に出てくる質問。
Usually RPET, once shipping weight is included — canvas is considerably heavier and that cost is easy to overlook. The exact crossover depends on construction, so give us the volume band and we can tell you where it sits.
12oz if the tote needs to read as durable in hand. Lighter weights cost less but are most of what separates a tote that gets reused from one that does not.
Slightly on first wash. Where the piece is expected to be laundered, pre-shrunk fabric is specified before sampling.
Either can, and neither does automatically. The claim rests on documentation for the specific material, which is confirmed per program before it reaches copy.
