What the actual option selection showed
We selected the 30# option on the actual EcoEnclose product page and observed PRK24-30, 24 in x 1200 ft, at $39. Selecting 40# changed the SKU to PRK24-40, the declared length to 900 ft and the price to $53. A base page amount is not evidence that every listed grade costs the same.
Avoid the mixed-variant bargain
Combining $39 with the 40#900 ft option would misstate that selected offer. Combining the $53 price with 1200 ft would also give the wrong denominator. Keep the price, grade, length and selected SKU captured together. The source verification screenshots and option observations are retained locally rather than inferred from a search snippet.
Keep the exact SKU
The observed unit costs are $3.25 per 100 ft for 30# and about $5.89 per 100 ft for 40#. That difference is not a protection ranking or proof of lower completed-pack cost. The papers have different grade and length declarations, and this site has not measured their consumption for an equivalent shipping result.
A meaningful comparison next step
Before ordering, reselect the actual grade and confirm current amount, availability and order unit. If a business needs a particular material specification, resolve that requirement first. Then compare its actual quantity and delivered cost. Do not let a low base price or a familiar family name silently substitute another variant in the purchase plan.
The selected 40#calculation
The actual 40#selection displayed 53 dollars for 900 ft, or about 5.89 dollars per 100 ft. The 30#selection displayed 39 dollars for 1200 ft, or 3.25 per 100 ft. These are two distinct observed variants. A correct comparison should show both grade and length so a reader can see why using the base page price for every option is wrong.
Do not infer a completed-pack saving
EcoEnclose discusses different material behavior in its packing-paper guide, but this site has not measured comparative consumption. A higher per-foot price could still produce a different actual process cost if a valid tested pack-out used a different amount. We do not fabricate those usage amounts to declare either grade more economical in practice.
Save the option label
The source verification selected 30#-24 in x 1200 ft and captured child SKU PRK24-30. That exact option label belongs with its price. A search result displaying only PRK24 and 39 dollars is incomplete evidence for the 40#variant. Retain the chosen option rather than relying on the parent family code when issuing a purchase order.
Recheck before repeating an order
A saved selected price is an observation on November 4, 2026, not a guaranteed future quote. Reopen the same grade and verify its current amount and availability. Do not use a different default option after a site redesign or assume every color/grade change preserves the price simply because the page address stays the same.
Keep a comparable requirement
If a specification calls for 40#paper, do not replace it with 30#solely to match the lower subtotal. Resolve the actual requirement with the responsible process owner or supplier. The site provides purchase arithmetic and source records; it has not certified that two grades satisfy the same protection, equipment or handling requirement.
